高庄煤矿1101水采工作面地表移动参数分析

Analysis of the Surface Movement Induced by the 1101 Hydraulic Mining Face in Gaozhuang Coal Mine

通过对高庄煤矿1101水采工作面开展地表岩移观测研究,获得了水采地表岩移参数,并与旱采岩移参数进行了对比,得出水采下沉系数在相似的开采条件下明显低于旱采的结论,并应用研究成果在开采沉陷土地治理等方面取得了显著经济效益。

Through the observation and analysis of the surface strata movement induced by 1101 hydraulic mining face in Caozhuang coal mine, the parameters of surface strata movement in hydraulic mining were obtained, and these parameters were compared with the ones in dry mining, finally a conclusion was drawn that under the same mining condition the coefficient of surface subsidence in hydraulic mining was obviously smaller than one in dry mining. The application of the studied results in the control of surface subsidence had reached obvious economy effect.
