利用新型材料治理井田地表裂隙的探讨

由于大同煤矿集团马脊梁矿上覆采空区地表裂隙发育,在矿井通风方式、采煤方法、小窑火区影响、气候变化等多种因素的共同作用下,回采工作面有害气体大量泄出。为克服这一重大安全隐患,探讨了采用新型化学材料与传统方法结合,对井田内的地表裂隙进行长效治理的方法,指出这一方法的实施,将会大大减少治理地表裂隙所需的工程量,并确保井下生产安全。

Probe into the Governance of Surface Cracks in the Minefield by Using the New Materials

Because of the development of surface cracks of overlying goaf in Majiliang Coal Mine of Datong Coal Mine Group,and under the combined action of various factors such as mine ventilation way,coal-mining method,small coal-pit fire zone influence,and climate change,etc.,harmful gas leaks out a lot from the coalface.In order to overcome this major potential safety hazard,this paper probes into the method for carrying out the long-efficiency governance of surface cracks within coalfield by adopting the combinati...
