摘要： 随着党的十九大中关于人与自然和谐相处概念的提出，环境问题越来越受到人们的重视。棋盘井利民煤矿地
处内蒙古自治区，地下矿藏资源丰富，地质条件相对适中，但伴随煤矿的采掘，地表形成诸多裂缝。通过对利民煤矿地
裂缝的成因机理及煤层地质构造的深入分析，对地表裂隙带结构进行深入分析，研究地表裂隙产生原因。运用单轴抗
压、流动性测试、凝固测试等方法对不同实验方案进行深入分析，选择并采用合适的封堵方法进行裂隙封堵，达到了封
堵地表裂隙带的目的。

Abstract: With the 19th National Congress of the Communist Party of China, the concept of harmonious coexistence between
man and nature has been put forward, and more and more people pay attention to environmental problems. Limin Coal Mine of
Qipanjin is located in Inner Mongolia Autonomous Region, with abundant underground mineral resources and relatively moderate
geological conditions. However, with the mining process of the coal mine, many fractures formed on the surface. Through the indepth
analysis of the genetic mechanism of the ground fractures and the geological structure of the coal seams in Limin Coal
Mine, this paper carried out in-depth analysis of the structure of the ground fracture zone, and studied the cause of the ground
fractures. Different experimental schemes were analyzed by uniaxial compression, fluidity test, solidification test and other
methods, and suitable plugging methods were selected and adopted to seal the cracks, so as to achieve the sealing effect on the
ground fracture zone.
