为能够最大限度的利用煤炭资源,同时又能保证周围建筑的使用功能,以鸡虎高速公路收费站车库楼地下煤炭开采为例,运用概率积分法的等价转换线积分方法,对煤矿已采工作面和未采煤层开采时对地表的影响分别进行计算,结合车库楼受损现状进行分析.研究结果表明:开采剩余资源,地表将发生多次的移动与变形,且累积的地表移动与变形各指标值均较大,已远远超过一般的砖混或框架结构建筑物的承受能力,所以不可对未采煤层进行开采.
In order to maximize the use of coal resources, but also to ensure the use of the surrounding buildings function, taking the Jigger Expressway toll station garage underground coal mining as an example, the use of probability integration method of equivalent conversion line integration method, The influence of mining face on the ground surface is analyzed separately and the damage status of the garage building is analyzed.The results show that the surface will move and deform many times when the remaining resources are mined, Deformation index values are larger, far more than the general capacity of masonry or frame structure of the building, it is not allowed to the mining of coal seams.
