摘 要:以15#煤层黄泥裹碎石顶板作为研究对象,在对15#煤层顶板地质力学评估的基础上,针对黄山煤业和掌石沟煤业15#煤层顶板黄泥裹碎石特征,采用棚式和锚网支护相结合的方式对其进行支护。结果表明:对于顶板破碎巷道,11#矿用工字钢半圆拱形钢棚可以有效解决巷道支护问题;对于顶板相对完整巷道,锚网支护可以很好地控制巷道的围岩稳定性。The mud gravel tunnel of the 15#coal seam was studied. On the basis of the geological mechanics evaluation of 15# coal seam roof, the roof features of Huangshan mine and Zhangshigou mine were analyzed. The connection of the shed support and the bolting with wire mesh was used. The result is that: the shed support of 11#mine steel can effectively solve the tunnel supporting, when the tunnel is mud gravel. The bolting with wire mesh can control the stability of surrounding rock of the tunnel.
