摘要
通过现场多种手段监测,揭示了综放开采影响期间沿空异形煤柱锚网支护留巷的矿压规律。研究表明,综放沿空留巷受采场矿压影响时间和程度随留巷煤柱宽度的增加表现出明显滞后现象以及位移和压力增长的不同步现象。
By various means of site measurement, the mining stress with respect to space-time is discovered on the roadway that is protected by an irregular pillar remained along the goaf in mechanized top-coal caving and supported by bolt-mesh technique. The study indicates that with the increase of the coal pillar width the peak mining stress delays its appearance and the increase of the displacement and stress are not synchronous.
