深井矿山有岩爆倾向的巷道加强支护研究

Reinforced support of drift with rockburst in deep mine

由于高应力、高温度等复杂的地质条件作用,深部开采诱发了各种地质灾害,尤其是岩爆产生的破坏影响尤为严重,不但给矿山生产造成了严重威胁,而且严重制约着矿山的生产能力及采矿成本。基于国内外发生岩爆矿山的地质及开采概况,对岩爆发生的主要影响因素进行了分析与探讨,并对有岩爆倾向性的井下巷道等工程提出了针对性的加强支护方案,为后续井下巷道的支护方式提供借鉴。

Due to complicated geological conditions of high stress and high temperature, some geological disasters are induced in deep mine, especially the serious rockburst. It not only causes serious threat to mine production, but also serious effect the mine production capacity and mining cost. Based on mine geology and mining conditions at home and abroad, the main influence factors of rockburst are analyzed and discussed. Then the reinforced support for underground drift with rockburst are put forward, which can provide reference for underground support of deep mine.
