煤层巷道过分叉区掘进支护工艺浅析及应用

Coal roadway bifurcation zone tunneling support measures analysis and application

随着煤炭企业生产规模的扩大,开采强度不断提高,对巷道断面及支护质量需求也随之增大。但在巷道掘进过程常常遇到不同的地质条件,影响正常的巷道的掘进。本文通过对巷道过煤层分叉区时不同的顶板条件,制定相应的掘进和支护措施,保证了工作人员的安全作业,确保了安全、快速、高效的通过巷道煤层分叉区。

With the expansion of coal production, mining intensity continuously improve and also increased the demand on the roadway. But in the roadway excavation process often encountered in different geological conditions, and affect the normal roadway boring. Through seam bifurcation area crossheading different roof conditions, development of excavation and support measures to ensure the safe operation of the staff, to ensure a safe, fast and efficient tunneling.
