大倾角特厚煤层综放开采覆岩运动特征研究

Research on overlying strata movement characteristics of fully mechanized top coal caving mining in large inclined and extra thick coal seam

本文以庞庞塔煤矿9-301综放工作面作为研究对象,通过相似模拟研究手段,对大倾角特厚煤层综放工作面回采过程当中覆岩运动特征进行分析研究,研究成果对大倾角特厚煤层综放开采具有理论参考意义。

In this paper,9-301 fully mechanized top coal caving face in Pangpangta coal mine is taken as the research object.Through the similar simulation research method,the movement characteristics of overburden rock in the mining process of fully mechanized top coal caving face with large dip angle and extra thick seam are analyzed and studied.The research results have theoretical reference significance for fully mechanized top coal caving mining with large dip angle and extra thick seam.
