新汶矿区孙村煤矿已经延伸到-1100水平,是我国煤矿采深最大的矿井之一。随着开采深度的增加,深部工作面的开采条件发生了很大变化,地压增大、煤层倾角大、断层多、温度升高、战线加长、生产系统复杂等开采条件,造成矿井生产能力低、准备工程量大、生产接续紧张,同时给安全生产带来了困难。通过在-1100后三采区和-1100前四采区跨断层联合布置,实现采区合理集中生产,提高了采区生产能力和经济效益,降低了万吨掘进率,为深部矿井复杂条件下安全生产和稳定发展提供了有力的技术保障。
Xinwen mine Suncun coal mine has been extended to the level of -1100, China’s mining is one of the largest mines. With the increase of mining depth, mining conditions in deep working face have undergone great changes. With the increase of underground pressure, large coal seam dip, more faults, higher temperature, longer fronts and complex production systems, the production conditions of mines are low , Preparing a large amount of work, continue to produce tension, at the same time to safety has brought difficulties. Through the joint arrangement of the three mining areas after -1100 and the first mining area -1100 across faults, the reasonable centralized production of the mining area is achieved, the production capacity and economic benefits of the mining area are raised, and the drilling rate of 10,000 tons is reduced. Under the complicated conditions of deep mines Safe production and stable development provided a strong technical support.
