摘要
煤矿开采岩层与地表移动规律研究,对合理留设保安煤柱、科学指导搬迁和保持企业的可持续发展具有重要意义。通过对开滦钱家营矿271观测站资料的分析,求取部分该矿厚冲积层条件下地表移动参数,以期有效指导"三下"采煤工作的开展。
Analysis of the rules of rock strata and ground surface movement in coal-mining has the vital significance for coal mining industry companies to arrange safety coal pillars,guide relocations,and keep sustainable development.This paper is based on the materials from No.271 Observatory of Qianjiaying Coal Mine of Kailuan Group,to evaluate the parameters of surface movement on deep alluvium basis,for the guidance of coal Mining Under Buildings,Railways and Water Bodies in the future.
