近二十年来,深水平煤层开采问题的意义日益增大。因为随着开采深度的增加,煤层赋存的矿山地质条件恶化,而且由于一系列自然因素对采煤工艺过程的综合影响,使采矿工作极为复杂化。 目前,深水平矿井(大于600米)的产量占井工开采产量的30％,而在顿巴斯矿区则占55％。 一些最深矿井的开采经验表明,矿压是使开采工作复杂化的最主要影响因素。在矿 In the past 20 years, the significance of deep horizontal coal seam mining has been increasing. Because as the mining depth increases, the geological conditions of the coal mine deposit deterioration, and due to a series of natural factors on the coal mining process, the combined effect of the mining work is extremely complicated. At present, the production of deep horizontal mines (greater than 600 meters) accounts for 30% of the production of the well workings, while it accounts for 55% of the production in the Donbas mine. Mining experience in some of the deepest mines shows that rock pressure is the most important factor that complicates the mining effort. In the mine
