在对支护现状分析的基础上,提出将提高锚杆支护的主动支护效果作为支护优化的方向。将锚杆支护三原则与矿井实际情况相结合,提出了锚杆设计参数,并对卸压工程进行了合理调整。工程实践证明,调整支护形式和卸压手段后,巷道支护效果和卸压效果均能够满足需求。
在對支護現狀分析的基礎上,提齣將提高錨桿支護的主動支護效果作為支護優化的方嚮。將錨桿支護三原則與礦井實際情況相結閤,提齣瞭錨桿設計參數,併對卸壓工程進行瞭閤理調整。工程實踐證明,調整支護形式和卸壓手段後,巷道支護效果和卸壓效果均能夠滿足需求。

on the basis of the analysis of the status of roadway support, proposed to take the improvement of the bolting support active supporting effect as the optimization direction. The bolt support three principles combined with the actual situation of mine, put forward the design parameters of anchor, and carried out a reasonable adjustment to the pressure relief works. The engineering practice proved that, after adjusted the support form and pressure relief means, the roadway support effect and effect of pressure relief can meet the demand.
