摘　　要：以鹤煤八矿近煤仓硐室开采变形为工程实例,采用理论分析、数值模拟和现场试验等研究方法对覆岩移动变形预计理论和技术进行了较为系统的研究和分析,最终确定最优方案进行开采试验。实测表明,煤仓附近的2202工作面回采结束后,煤仓壁和硐室并没有受到较大影响,采出煤炭10.2万t,增加5100万元的产值,给矿井带来了可观的经济效益。Shaft coal pocket mining deformation is taken as the project application background on No. 8 Coal Mine of Hebi Coal Industry（Group） Co. , Ltd. , the methods of theoretical analysis＇ numerical simu lation and field test were used to more systematically research and analyze the movement and deformation predicted theory and technology of rock. Finally, the optimal mining program were used. Measurement showed that the coal pocket and chambers were not affected ＇after 2202 working face finished near it, which stopping 102,000 tons coal, increasing output value 51 million Yuan, to bring good economic benefit to the coal mine.
