摘要
水压爆破传能效率高,水楔作用效果明显,破岩能力强。然而,由于煤矿的特殊性,水压爆破在煤矿应用研究较少,而且基本以研究相应的岩石为主,通过应用数值模拟技术,研究了水压爆破在煤体中的爆破机制,为实际应用提供依据。
Water pressure blasting energy transfer efficiency, water wedge effect is obvious, rock breaking ability. However, due to the particularity of coal mine, the application of hydraulic blasting in coal mine is relatively small, and the basic rock is mainly studied. The blasting mechanism of hydraulic blasting in coal is studied by numerical simulation, provided abasis for practical application.
