针对鸡西东海煤矿采深1160 m条件下,巷道产生底臌现象的实际情况,对32号层五采区四段回风平巷,应用底板锚杆支护进行研究。结果表明,在原有巷道支护的基础上加打底锚能够有效地控制底臌和巷道两帮的移近量,减少巷道围岩的变形量,保证巷道的稳定性,从而保证生产的正常进行。
針對鷄西東海煤礦採深1160 m條件下,巷道產生底臌現象的實際情況,對32號層五採區四段迴風平巷,應用底闆錨桿支護進行研究。結果錶明,在原有巷道支護的基礎上加打底錨能夠有效地控製底臌和巷道兩幫的移近量,減少巷道圍巖的變形量,保證巷道的穩定性,從而保證生產的正常進行。

Considering the actual situation of roadway floor heave in Donghai Coal Mine in Jixi , with the mining depth of 1160 m , the paper studies the No .32 recovery roadway among the five mining area to which the plate anchor is applied .The results show that it can effectively control the floor heave based on original support and the applied plate anchor .The two sides of roadway come closer , which decreased the amount of surrounding rock deformation and ensure the stability of the roadway , thus ensuring the normal production .
