cdc mining electrical equipment explosion protection explosion protection refers to techniques used to minimize the potential for electrical and electronic equipment to create an ignition while operating in a hazardous location (hazloc). a hazloc refers to atmospheres containing flammable gases or vapors and/or combustible dusts. in particular, u.s. coal mines and other gassy mines are required to use equipment in certain areas of the mine that has been approved by the mine safety and health administration (msha) for use in a methane and coal dust environment to limit the risk of the equipment creating an ignitioncapable spark or a thermal energy ignition. there are three basic means of providing explosion protection for equipmentthese are, precluding the gas (explosive mixture) from reaching the circuitry, limiting the energy of the circuitry so that ignition is not possible, or containing the explosion to the area immediately surrounding the circuitry so that it cannot propagate into the surrounding environment. the nioshspons see full list on cdc.gov the mission of the niosh research program for the mining sector is to eliminate occupational diseases, injuries, and fatalities among workers in the mining industry. therefore, explosion protection research at niosh is focused on continually improving the safety of miners. certain explosionprotected equipment used in other countries and industries to improve health and safety are not available for use in the u.s. coal mining industry because this equipment has not been certified as permissible (explosion protected) as required by u.s. mining law. research into the differences in explosion protection requirements was initiated to help understand the technical differences between equipment that meets iec standards and us mining criteria. with this in mind, niosh chose to evaluate an explosion protection technique which both msha and the iec recognize: twofault intrinsic safety (is). in fact, both the iec standard and msha approval criteria for is equipment evolved from the same orig see full list on cdc.gov as mentioned earlier, of the 13 explosion protection techniques that are used in other industries, there is only one other than 2fault intrinsic safety that is recognized by msha. that is the use of explosion proof (xp) boxes, these are referred to as flameproof (fp) containers internationally (iec 600791)the purpose of which is to limit the explosion to inside the container so it does not propagate into the surrounding environment. acceptance of flameproof as an equivalent to msha xp criteria (30 cfr 7 and 18) would require making an equivalent level of protection determination. unlike the case with the comparison of is standards, the principle differences which bear on the fundamental protection mechanism are significantly more conservative in the msha standard as identified in report the department of labor, mine safety and health administration, report of investigation, part 6 equivalency review and comparison: msha and iec explosionproof enclosure standardspdfexternal (m see full list on cdc.gov the fundamental question to be answered, in the context of current u.s. mining law, is how can new explosion protection techniques be introduced without reducing the level of protection afforded the miner? such a comparison has proven very difficult to make without consideration of all factors contributing to the risk of an explosion, which include not only the equipment protection technique, but the reliability and effectiveness of the mine ventilation, monitoring of the atmosphere, and maintenance of the equipment, among other things. it is clear that the two techniques explicitly recognized by u.s. mining law provide some of the highest level of explosion protection available on an equipment basis, but does limiting explosion protection approvals to these two techniques preclude the introduction of new technologies that could improve safety and health in other areas?

determination of the initial mobile equipment fleet is an important step in the overall underground mine design process, and is typically based on the production targets, mining methods, and stope dimensions. not only does the mining equipment employed in the operation impact the overall mine productivity, ventilation requirements, and maintenance considerations of the entire mining operation, but also the overall project economics. the initial capital cost calculations, annual operating costs, equipment replacement considerations, and other financial implications play a significant role in establishing an accurate forecast of the netpresentvalue of the mining operation. through the collection and analysis of pertinent data, the use of relevant performance measures, and related studies, mine planners can identify the most costeffective opportunities maximize productivity and the span of the equipment life, as well as reduce the overall cost. as there is inherent variability a see full list on minewiki.engineering.queensu equipment selection for a hardrock mine typically begins with or soon after the planning parameters of the stoping operation is completedtherefore, equipment used for stoping should be suitably sized for the stope dimensionsand the characteristics of the orebody. however, it is also impractical to commence mine planning and scheduling without a working concept of the relative type and size of equipment that may be employed. all underground deposits require a method of accessing the orebodythus, multiple factors should be known, such as daily production rate and the equipment selected for development and production, with the associated sizing, utilization, and costing data to assist in determining the best layout. most modern underground mines typically operate with fleets of mobile production equipment that include, but are not to: loadhauldump machines (lhd), haul trucks, drill jumbos, longhole drills, rock bolting machines, and other ancillary equipment. all pieces see full list on minewiki.engineering.queensu loadhauldump (lhd) vehicles, also referred to as scooptrams, loaders, and muckers, are the fundamental mobile component of an underground mining operation. they are fourwheeled, centrearticulated, bidirectional, rubbertired machines that can be diesel or electric powered and are designed to fit under restricted heights and narrow areas in an underground mine. the centrearticulation feature allows for the machine to have high maneuverability and a small turning radius to adhere to the designated stope sizing constraints. furthermore, lhds are versatile as their small turning radius and bidirectional features enables for switchbacks to be employed. they are typically selected to complement the size of the fragmented material in a mining environment. lhds differ from frontend loaders due to their narrow breadth and ability to maintain a lowprofile, and they can productively carry a load in their bucket for up to 200 m. they tend to devote more time travelling than frontend see full list on minewiki.engineering.queensu haul trucks are typically dieselpowered machines that transport material to and from surface, development stopes, headings, and draw points. there are three main types of trucks that are employed to adhere to different requirements: tractortrailer units that are typically sidedumping and can be assembled as an underground road train, rigidbody reardump trucks, and articulated reardump trucks that are designed to have a low profile. an articulated, reardump truck is one of the most common trucks in an underground mining environment, as they are highly adaptable to rough terrain and typically possess a low profile. see full list on minewiki.engineering.queensu jumbo drills are a diesel powered mobile carriage that typically support 1 to 3 drills. they are used for rock excavation and have an articulated transporter and an electrically powered hydraulic pump to control the boom(s) and rock drill(s). the size of the opening dictates the number of booms the jumbo will need to have. single booms are used in small headings or narrow veins, and can cover face dimensions from 6 m2 to 30 m2. jumbo drills with two booms can cover an area ranging from 8 m2 to 100 m2, which makes it the most common selection due to their versatility. three boom jumbos are rarely employed due to their larger size and increased complexity of operation. jumbo drills must possess the ability to reach the limits of the largest excavation, which is usually determined by the production drills and trucks. the reach of a jumbo drill also sets a limit of cut and fill slice thickness or stope width.furthermore, the jumbo drill must be able to reposition to ensure precise drill see full list on minewiki.engineering.queensu production drills are employed to drill blast holes in a circular pattern around a drift. production drills often control stope dimensions, and are most commonly used in block caving, sublevel caving, sublevel open stoping, and vertical crater retreat mining operations. the capabilities and limitations of production drills (i.e. the ability to drill a certain length while remaining sufficiently accurate, or reaching a certain height) can dictate the amount of drill deviation that will occur, which will affect dilution or poor fragmentation.the type of production drill utilized in a mining operation will depend on the drilling and blasting requirements, rock mass characteristics, and the stope design. there are two primary types of production drills: longhole drills and downthehole (dth), which are also referred to as inthehole (ith) drills. see full list on minewiki.engineering.queensu a rockbolting machine resembles a jumbo drill and may employ the same carrierhowever, they are typically composed of a fourwheeldrive, articulated, scissorlift platform whereby the rock bolting is conducted using a handheld rock drill. development jumbo drills can also be used to install rock bolts and meshin these cases, the boom must have the capability to turn 90 to the axis of the carrier, and a splitfeed boom may be required to extend the boom to full length. this capability adds significant complexity and costs to maintenance, and the additional weight may result in bolting inaccuracy. the size of a rockbolting machine should guarantee suitable proximity to the development or production heading. one prevalent issue with selecting a rockbolter is that they tend to be too small to suit the heading size and subsequently are unable to reach all of the designated areas in the heading. rockbolting machines may be slower and less mobile than jumbodrillshowever, they c see

equipment listed above. other pieces of equipment that may be considered include, but are not to: 1. scalers: suitable for headings that are between 4 6 m high. 2. shotcretemachines: these machines should be mobile, have an effective boom length, and have remotecontrol capability to remove human involvement in the unsupported areas. 3. frontend loaders: they are excellent for mucking but are extremely poor when required for haulagetherefore, the use of lhds are generally selected over frontend loaders. 4. rail equipment: the use of rail equipmentalthough still employed in some mining operations, is rapidly diminishing due to the meticulous and detailed planning required for location, costing, manufacturing, cycle times, gradients, safety, sizing, and ventilation requirements. furthermore, soft rock mining incorporat see full list on minewiki.engineering.queensu the selection of the mobile equipment fleet for an underground mining operation is a vital part in determining the overall project net present value (npv). as the underground mining industry is extremely capitalintensive, an analysis needs to be conducted on equipment fleet before any investments are made to ensure that the justification for purchase is quantified in advance. a minimum rate of return (marr) or the weighted average cost of capital(wacc) are typically the primary hurdle rates that new mining companies strive to exceed to allow for a favourable rate of return and positive npv to be achieved. conducting a lifecycle cost analysis is a recommended method for evaluating, comparing, and selecting equipment. this procedure examines the cost associated with a piece of equipment over its entire life, which includes the initial purchase, the production cycle, and disposal. this analysis allows for a determination of the best equipment selection, as the machine with the lowest see full list on minewiki.engineering.queensu the mining industry is extremely capitalintensive, especially when implementing bigger equipment with larger capacities to increase production rate. however, low commodity prices have forced companies to discover methods in which to decrease their overall unit costs by improving equipment productivity. one way to accomplish this is to utilize equipment more effectively and efficiently. an industry rule of thumb productivity breakdown for various activities is displayed in figure 13. therefore, equipment utilization (eu) is an integral measurement that can not only evaluate mobile equipment performance, but also reduce production costs and improve the profitability of a mine. see full list on minewiki.engineering.queensu an overview of modern mining equipment types constro among all the equipment employed in the mining sector, earth moving equipment is most widely used. most used earthmoving equipment that is used to help move earth and excavate the land in mining are excavators, backhoe loaders and dump trucks. peralatan maria
