寸草塔二矿3-1煤层矿压显现实测研究

Strata Behaviors Survey in 3-1 Seam of Cunchaota 2nd Mine

寸草塔二矿过去主要采用房柱法开采,为了适应国家和内蒙经济发展对煤炭工业的需要,同时解决资源回收率低的关键问题,在集团公司和分公司的支持下将采煤方法变为长壁综采工艺。为此,结合寸草塔二矿3-1煤层首采工作面的开采,对开采过程中采场矿压显现规律实施观测,以期给今后的工作面巷道布置与支架选型提供重要的决策依据。

To raise coal recovering ratio, cunchaota 2nd mine replaced the mining method with long - wall fully - mechanized mining. The strata behaviors in 3 - 1 seamwas monitored to obtain a foundation for entry layout and supporter selechion.
