摘要(Abstract):

近年来,北京矿冶研究总院在深入开展束状孔爆破理论与技术研究的基础上,创新性地开发了束状孔当量球形药包爆破技术与束状孔变抵抗线爆破技术,并广泛应用于不同条件地下矿山的开采中,取得了良好的效果。本文结合冬瓜山铜矿和华锡集团铜坑矿地下开采工程,介绍了上述两项爆破技术的原理、特点、实际应用效果与扩展领域,具有一定的学术与应用价值。
In recent years,based on deeply studying theory and technology of bundle holes blasting,Beijing General Research Institute of Mining & Metallergy developed the innovative technology of the equivalent spherical cartridge bundle holes blasting and variable resistance line bundle holes blasting,widely used them in the underground mines with different conditions,and achieved good effect.The principle,features,practical application effect,and expansion areas of the two blasting technology were introduced in the underground mining projects of Dongguashan copper mine and Huaxitongkeng mine,which have certain academic and practical value.
