摘要: 为对建筑物下压煤进行开发利用,同时保护地面建筑物安全,以邯郸矿区某矿2103工作面工业广场下采煤为研究区域,采用概率积分法对地表变形进行预计,评定了主要建筑物的损害等级,并给出了合理开采的建议。研究表明:工业广场主要建筑物均不同程度地受到变形的影响,其中宿舍楼破坏等级为Ⅲ级,食堂、煤仓破坏等级为Ⅱ级,机修厂房破坏等级为Ⅰ级,结合地面监测结果可知,整个工作面开采地表变形预计结果与实际情况较吻合。

Abstract: In order to conduct the development and utilization of coal under buildings,while protecting the safety of ground buildings,taking the industrial square of the 2103 working face of a mine in Handan mining area as the study area,the surface deformation is predicted by using the probability integration method,and the evaluation of the main building damage grade is done,besides that,some relative suggestions about reasonable exploitation are given.The study results show that the main buildings of the industrial square are affected by the surface deformation in different levels,the damage grade of dormitory is Ⅲ level,the damage grade of canteen and coal bunker is Ⅱ level,and the damage grade of the machine repair shop is Ⅰlevel.The above evaluation results is basically consistent with the surface monitoring results,which further indicated that the evaluation results of this paper is reliable.

Key words: Coal mining under buildings, Probability integral method, Deformation predictio, Tilt monitoring
