由于露天开采破坏的土地复恳量大而产生生态危机,所以近年来库兹巴斯矿区以井工开采法作为其采煤的发展远景。采用井工开采法时,周围环境的生态破坏可缩减到最低限度。 显然,利用高效的综采机组强化开采缓倾斜和倾斜中厚和厚煤层要求高度的井下工程年延深速度。这将导致矿山地质条件的恶化,从而对矿井采煤工作的技术经济指标产 In recent years, KuzBas mine has adopted the method of mining as the development prospect of its coal mining due to the ecological crisis caused by the large quantity of land damaged by open-pit mining. When using underground mining method, the ecological damage to the surrounding environment can be reduced to a minimum. Obviously, the use of highly efficient fully mechanized mining units to enhance the slow mining and inclined thick and thick coal seams require a high degree of downhole depth of the project. This will lead to the deterioration of the geological conditions of the mine, so that the technical and economic indicators of coal mining work
