The Numerical Simulation Study on Mine Pressure Behavior Laws at Fully-mechanized Mining Face of Complicated Structure Coal Seam

为解决澄合矿区复杂结构煤层开采过程中存在的液压支架选型合理性等问题,以该矿区5208综采工作面研究背景,通过现场矿压观测、数值模拟等手段分析研究了矿压显现规律及覆岩的冒落裂隙带发育高度演化特征。其结果为澄合矿区复杂结构煤层综采支架合理性选择以及相似工作面的高效安全生产提供科学依据。

In order to solve the rationality problems of hydraulic support selection in complicated structure coal seam mining process of Chenghe mining area, taking No. 5208 fully - mechanized mining face as research background, through the method of field pressure ob- servation and numerical simulation, the paper analyzes the mine pressure behavior laws and the evolution laws of development height of overburden fractured zone. The result provides scientific basis for reasonable selection of mechanized mining support in complicated structure coal seam of Chenghe mining area and efficient and safe production of the similar working face.
