摘要
煤炭开采会造成岩体变形和破坏,造成地表变形移动。为获取地表移动参数,通过在综放工作面地表设计并布设岩移观测站,对地表观测成果进行整理分析,获得工作面综放开采地表移动变形的相关参数,走向移动角为74°,倾向上山移动角为79°,倾向下山移动角为77°,为矿井今后留设村庄等构筑物保护煤柱提供科学依据。
Coal mining will cause rock deformation and damage,resulting in surface deformation and movement.In order to obtain the surface movement parameters,through the design and layout of rock movement observation station on the surface of the fully mechanized top coal caving face,the surface observation results are sorted and analyzed,and the relevant parameters of the surface movement and deformation of the fully mechanized top coal caving face are obtained.The strike movement angle is 74°,the inclination up mountain movement angle is 79°,and the inclination down mountain movement angle is 79°.It can provide scientific basis for protecting coal pillars of villages and other structures in the future.
