摘要
通过对煤矿输送机巷道进行长期的监测与调查,分析了形成底鼓的原因及底鼓的特性,得出该巷道的底鼓是由于底板没有支护,为了释放巷道的应力和变形,破碎围岩经过挤压进入巷道,属于挤压流动型的底鼓。通过利用综合治理技术对该巷道进行治理后发现,该技术能够有效地控制底鼓,而且对于两帮围岩力学性能进行改善,变形速率大大降低。
Through to coal belt conveyor roadway conducted long-term monitoring and investigations,analyzes the causes and characteristics of the formation of the bottom of the drum after the kick drum,come the end of the tunnel floor drum is due to no support,in order to release the stress of the roadway and deformed,broken rock after squeezing into the roadway,are squeezing the bottom of the flow-type drum.Through the use of integrated management techniques to govern the roadway and found that the technology can effectively control the kick drum.
