山西芦子沟煤业矿井副斜井延伸段设计与施工方法

Design and Construction Method of Auxiliary Inclined Shaft Extension Section in Shanxi Luzigou Coal mine

为保证矿山煤层连续开采,在不建造新井筒的情况下,将副斜井进行延伸,通过对水文、地质等条件的勘察,针对矿井实际情况,采取副斜井延伸综合施工方法。实践结果显示,副斜井延伸效果良好,可将工作效率提升30%左右,施工过程保证了良好的安全性,有效控制裂隙出水及排水问题。

In order to ensure the continuous mining of coal seam, the auxiliary inclined shaft is extended without building a new shaft. Through the investigation of hydrological, geological and other conditions, according to the actual situation of the mine, the auxiliary inclined shaft extension comprehensive construction method is adopted. The practical results show that the extension effect of auxiliary inclined shaft is good, and the work efficiency can be improved by about 30%. The construction process ensures good safety, and effectively controls the water and drainage problems of cracks.
