复杂条件下薄煤层综采方案研究

Research on the fully mechanized coal mining scheme of thin seam under complicated conditions

为了解决某煤矿1160采区地面有村庄、工厂、学校且煤层底板距奥灰较近的实际问题,通过理论分析和计算确定1160采区条带法开采,工作面采出宽度为:基岩厚度30 m以下区域,条带采出宽度30 m,基岩厚度30 m以上区域条带采出宽度为40 m;通过分析认为1160采区16、17煤层开采的安全性较高,正常情况下无突水危险。

In order to solve the actual problem that 1160 mining area of a coal mine locates under villages, factories, schools and coal seam floor is close to Ordovician limestone, through the theoretical analysis and calculation, determine that 1160 mining area use strip mining working face, the mining width is 30m in the area that thickness of bedrock is below 30m, the mining width is 40m in the area that the bedrock thickness is above 30m, the analysis show that the mining security of 16, 17 coal seam in 1160 mining area is high, and no water inrush risk under normal circumstances, finally according to 1160 mining area codition, put forward the floor water control measures.
