煤矿开采中巷道支护技术的应用探讨

Discussion on the Application of Roadway Supporting Technology in Coal Mining

结合实例分析了高预应力锚杆支护的具体工艺过程,并且对高预应力锚杆支护和锚杆支护进行了对比,通过监测数据得出,当采用高预应力锚杆支护工艺之后,巷道顶板结构的下沉量较之前采用锚杆支护时减少了84%左右,而巷道两帮结构的移近量较之前采用锚杆支护时减少了77%左右,支护效果显著。

The specific process of high prestressed bolt supporting was analyzed based on an example,and the high prestressed anchor support was compared with the anchor rod support in this article.It is concluded through the monitoring data that when the high prestressed anchor support technology is adopted,the subsidence of roadway roof structure reduced by 84%compared with the previous use of bolt support,while the proximity of the two sides of tunnel structure decreased by about 77%compared with the previous use of bolt support,the supporting effect was significant.
