煤层厚度稳定性是影响采煤方法、布局及采煤效益的重要因素之一。根据钻孔资料和矿井生产资料,对潘一矿及谢-李矿深部井13-1煤层厚度稳定性进行分析。结果表明,研究区13-1煤层厚度稳定性随深度加深而趋于稳定。并运用煤岩力学性质在浅部与深部的差异对这一现象进行解释。 The stability of coal seam thickness is one of the important factors that affect the coal mining method, layout and coal mining benefit. According to the borehole data and mine production data, the stability of coal seam thickness in Pan-1 mine and Xie-Li mine deep well is analyzed. The results show that the thickness stability of coal seam 13-1 in the study area tends to be stable with the deepening of depth. This phenomenon is also explained by the difference between shallow and deep parts of the mechanical properties of coal and rock.
