薄煤层群下位煤层开采矿压显现与控制技术研究
Research on mining pressure manifestation and control technology of lower coal seams in thin coal seam groups
摘要
Abstract
Taking the No.431401 working face of Liangshuijing Coal Mine as engineering background,and the measurement and analy-sis of mine pressure,analysis of the pressure in the mining area,and the calculation of the support resistance were carried out.The sup-porting effect of the support in the working face was analyzed through a combination of on-site measurements and theoretical calcula-tions.The results show that the pressure range of the No.431401 working face is concentrated in the middle,and the pressure range of roof is 35～42 MPa.The maximum stress variation of the advanced support pressure on the working face is 1.66 MPa,and the increase is not significant.Based on the movement law of the overlying rock in the 4-4 coal seam,the support meets the requirements mine pres-sure control in the mining area,and has good adaptability.关键词
