摘　　要：本文以吉林省三合城村玄武岩台地采空塌陷为例,通过对比分析,发现由于玄武岩盖层的存在,玄武岩台地采空塌陷有其特殊性,概率积分法计算结果与塌陷实际情况差异较大,但水平变形最大区域与裂缝带的分布位置却有着良好的对应关系。进而,本文总结了玄武岩台地采空塌陷地表变形的一般规律,以期对今后玄武岩台地采空塌陷的预测与防治工作有一定参考价值。Taking mining subsidence in basalt platform in Sanhecheng village of Jilin province for example,through the comparative analysis,the paper finds that mining subsidence in basalt platform has its unique characteristics,because of basalt cover's existence,and the calculation results of probability integral method is very different from the actual situation of mining subsidence,but maximum horizontal deformation region and the position of ground fissure has a good corresponding relationship.On these bases,the paper summarizes the general pattern of surface deformation of mining subsidence in basalt platform.It is expected that it has a certain reference value to prediction and prevention in surface deformation of Mining subsidence in basalt platform in future.
