摘要
基于开滦矿区地表移动观测站的大量实测资料,分析得出了浅部(小于400m)与深部(大于400m)开采条件下的地表移动参数。回归分析了地表移动角量参数、预计参数与地质采矿条件之间的相关关系,建立了其间关系的经验公式,对正确指导开滦矿区安全生产、合理开展"三下"采煤具有重要意义。
Based on lots of observation data of surface movement observation station in Kailuan mining area,the surface movement parameters under the conditions of shallow mining（less than 400m）and deep mining（more than 400m）are obtained.The relations between the angle parameters and prediction parameters of surface movement and geological mining conditions are researched by regression analysis method.The experience formula for the angle parameters and prediction parameters of surface movement is established,which has important significance for correctly guiding the safety production of Kailuan mining area and reasonably developing＂three unders＂mining.
