水胶炸药在石湖矿业公司开拓工程中的应用

Application of water gel explosive in development work of Shihu mine

针对石湖矿业公司开拓工程现状及井巷内淋水较大的工程实际,通过SHJ-M101型水胶炸药与矿山掘进工程中普遍使用的2#岩石铵锑炸药的对比,在竖井二期延伸开拓工程中使用了水胶炸药。工程应用实践表明,SHJ-M101型水胶炸药防水抗潮性能好,不仅提高了工程的起爆率和月进尺,而且减少了通风时间,加快了施工进度。

Aiming at the current status of development work and moisture shaft in Shuhu mine, No. 2 rock am- monium antimony explosive was replaced by SHJ - M101 water gel explosive after detailed comparison in the 2nd stage entending development work of the shaft. It was proved that the water gel explosive had good waterproof and moistue resistance performance. Both the percentage of initiation and monthly drilling footage was enhanced, while the ventila- tion time was cut.
