薄煤层综采回采巷道支护技术

Support Technology of Fully Mechanized Mining Roadway in Thin Coal Seam

结合斜沟煤矿薄煤层工作面具体地质情况,对回采巷道围岩变形破坏原因进行分析,确定薄煤层工作面合理的支护方式和支护参数。为检验支护效果,在巷道内进行测点监测。监测结果表明:薄煤层综采回采巷道围岩逐步趋于稳定,巷道变形量明显下降,确保了回采巷道的安全使用和工作面的安全开采。

In this paper,the specific geological conditions of thin seam coal in Xiegou Coal Mine are analyzed to analyze the causes of deformation and failure of surrounding rock in mining gateway.The reasonable support mode and supporting parameters for thin coal seam working face are determined,in order to test the support effect in the tunnel measuring point monitoring.The monitoring results show that the surrounding rock of the fully mechanized coal mining gateway in the thin coal seam gradually becomes stable and the deformation of the tunnel decreases obviously,ensuring the safe use of the mining gateway and the safe mining of the working face.
