To dig a pit located in mountainous regions and technologies in mining in our country also works to ensure the development of technical, scientific and production enterprise in foreign countries are given significant attention by the community. Tools and methods to dig out mine works has been constantly improving, expanding the field of effective application of available technologies. In these areas the use of which will ensure the transition of the open pit coal reserves lahim dolzarblashadi more. Costs the total capital costs associated with the build up of mineral deposits 50-60% of make up for it. Therefore the development of effective detection methods and schemes of mining and economic to choose the optimal scheme is one of the important tasks. The mining area of the deposit or the opening of the other block on the use of technology significantly related to the investment aspects.
Investment network in the conditions of a shortage on the opening of the mining area is used a lot in the implementation of the option (the vertical stvollar angle stvollar, shtolnyalar recorded lahim of a combination of a) reduced construction and commissioning of new facilities are required to be of the period. Thus, the angle stvollar of the machines (mechanical method) and the coal reserves is much preferred to opening through the transition. Also in the bottom angle of gorizont mining lahim (uklon) pass extraction of coal reserves to prepare supporting their weight with mass use of gorizont kontsentrasiya elitishni mining, mining laximlarini the use of modern methods of keep (periods a and a concrete sochma mustaxkamlagichlar) it may also include.
Mining companies in Central Asia are mainly located in mountainous areas, where high-altitude signs and low-altitude relief (1100-23 00m), sudden changes in temperature, snow, which complicate the construction of roads, construction and delivery of industrial materials, equipment, selection and construction of industrial sites. tectonic processes characterized by climate, energy, communication routes, lack of manpower, underdevelopment, overgrazing, presence of twisted structures, landslides, cracks, crushing zones, characterized by accumulation and migration, large amounts of precipitation leading to landslides and floods characterized by specific properties.
In some cases, due to the high flow of groundwater, it is not possible to effectively pass the opening and preparation solder, which decreases the slope. Lowering the water level by pumping through wells or using special methods (tamponing, freezing, etc.) is a very costly measure, which leads to the impossibility of mining some plots or a significant loss of time and resources.
Based on the generalization and analysis of opening schemes and open pit mines, the main directions of reducing the cost of opening mines in mountainous areas were identified, and they are the widespread use of precast concrete anchor reinforcement to reduce the use of scarce materials (wood, metal). the use of pre-screened and hardened rock dumps for the construction and expansion of sites, the use of self-propelled equipment, the rapid transition of mining laxatives, the use of floor tunnels equipped with elevators with capital and operating costs 3-5 times lower than vertical schemes Expanded, reconstructed and partially restored geology in the opening schemes - the widespread use of prospecting, the expansion of the use of gravity transport in the unloading of rudospusk and rocks, etc. received
