近距离煤层沿空留巷巷旁支护技术实践

Practice on Roadside Support Technology in Gob-side Roadway with Close-distance Coal Seam

以汾西矿业集团中兴煤业采用高水速凝充填沿空留巷工程为实例,分析巷旁支护体作用机理;采用数值模拟方式确定巷旁支护体宽度;采用对拉锚杆技术稳定控制了巷旁充填体成型;为矿井高水充填提供了技术经验借鉴。

Taking the construction of high-water and rapid-hardening backfilling in gob-side roadway of Zhongxing Coal Industry Co.for example,the author determines the width of roadside support body through numerical simulation by analyzing the action mechanism of support body,and proposes the anchor-stayed technique in controlling the filling body forming.
