寸草塔二矿31煤首采面矿压显现规律研究

摘要

以31煤首采工作面为研究对象，针对其特有的地质条件，通过制定专门的矿压现场观察、实测研究方案，认真分析并总结了31101综采工作面初采、正常回采、末采时的全过程矿压显现规律，同时结合矿压显现规律对现有支架阻力适应性进行了评价。%Based on the geological conditions of the first fully mechanized mining face in Cuncaota№2 Coal Mine, the mine pressure observation plan was research, the strata behaviors law of№31101 face in the whole mining period was observed. At last, combined with the strata behaviors law, the adaptability of hydraulic supports was evaluated.
