煤炭开采的强化导致采矿工程深度的增加,从而带来一系列困难:矿压增大,瓦斯含量增加,温度上升,煤、岩石和瓦斯突出数量和强度都增大.此外,还必须开采薄煤层.需要进一步指出,井工开采法对周围环境还有不良影响.例如,在顿巴斯为处理矸石每年需要拨出将近500公倾土地.现有的采煤工艺对一定的深度有效,并不能解决大深度复杂的矿山地质条件下强化回采的问题.
The intensification of coal mining leads to an increase in the depth of mining engineering, resulting in a series of difficulties: the increase of mine pressure, the increase of gas content, the increase of temperature, the increase of the quantity and intensity of coal, rock and gas outburst, and the exploitation of thin coal seams It needs to be further pointed out that the underground mining method has an adverse effect on the surrounding environment, for example, nearly 500 km of land is allocated annually for the treatment of gangue in Donbas.The existing coal mining technology is effective to a certain depth and can not To solve the large depth and complexity of mine geological conditions of enhanced recovery.
