综放工作面矿压规律及控制技术

Research on the Strata Behavior Regularity and Control Technology of the Fully Mechanized Caving Faces

在对某煤矿2401工作面矿压观测数据的计算处理及理论分析的基础上,研究了该综放面的矿压显现规律和回采巷道表面位移变化规律,并对支架适应性进行了分析。结果表明,所选支架合理、适应性较好,可为同类条件下的矿压规律及控制和支架选型提供参考。

Based on computing and analyzing the mine pressure observation data of 2401 working face, the strata behavior regularity and the surface displacement regularity of mining roadway are researched, besides that, the the adaptability of powered supports are analyzed. The research results show that, selecting of powered supports are reasonable and adaptability of the powered supports are good, which can provide a reference to the similar conditions for controlling of the mine pressure and selection of the hydraulic supports.
