龙宫煤矿2号煤层运输巷道支护参数的研究

Study on Supporting Parameters of Transport Roadway in No.2 Coal Seam of Longgong Coal Mine

通过对龙宫煤矿2号煤层坚固性测定,得出了"该煤层强度较低"的实验结论,因此对该运输巷道支护进行数值模拟分析及参数计算,找到了该巷道的最佳支护方案及参数。通过在运输巷道实际施工中的应用,验证了所计算支护参数的正确性,即在提高巷道支护强度基础上,也降低了企业材料及人员的施工成本,对保障巷道后期的作业安全具有重要意义。

Based on the determination of the firmness of No.2 coal seam in Longgong Coal Mine,the strength of the coal seam is low,the numerical simulation analysis and parameter calculation of the supporting parameters of the transport roadway are carried out,and the best supporting scheme and parameters are found.Through the application in the actual construction of transportation roadway,the correctness of the calculated support parameters is verified.On the basis of increasing the support strength of roadway,the construction cost of enterprise materials and personnel is also reduced.It is of great significance to ensure the safety of roadway in the later stage.
