| Abstract: | Based on the engineering background of No.1 Coal Mine of Huangling Mining Co., Ltd. 807 air intake chute, through theoretical analysis and calculation, the support strength at the end of heading face has been determined to be 37.71 kPa. Combining with the actual geological conditions of heading, the temporary support group of ZL2×1800/24/32 type advance temporary support has been adopted for temporary support. Through practical application, the temporary support can improve the driving speed on the basis of ensuring safety, and has good application effect. |
