通过对区内工作取得的大量基础性资料进行整理,系统分析了区内开采技术条件。认为该区矿床在自然流场下,与上、下含水带均无直接水力联系;顶、底板稳定性在横向上具有多变性;区内矿井多为高瓦斯矿井及煤与瓦斯突出矿井;除局部地区存在一、二级高温区外,其他均属于地温正常区;区内各煤层均为易自燃煤层-不易自燃煤层,煤尘具有爆炸危险性。
Through a great deal of basic information obtained from the work in the area, the technical conditions for mining in the area are systematically analyzed. It is concluded that there is no direct hydraulic connection between the deposits in the natural flow field and the upper and lower hydrosalks. The top and bottom stability of the deposit is variable in the horizontal direction. Most of the mines in the area are high-gas mines and coal and gas outburst mines. In some areas, there are first and second high temperature areas, while the others belong to the normal ground temperature zone. All the coal seams in the area are easily-ignited coal seam, which is not easy to cause spontaneous combustion and coal dust has the risk of explosion.
