利用炸药爆破一直是岩石破碎的主要手段．尽管在非炸药破碎领域已作了大量努力，然而仍可有把握地预见在未来将继续利用炸药进行爆破。在过去的一些年，炸药工业已显著成熟，同时用户对炸药性能和质量控制亦提高了要求．炸药性能可加以调节以适应一定的爆破环境，且仪表可提供有用的信息以使爆破优化．针对爆破代化已研制出可调节作用于岩体的冲击能与膨胀能之比的可控非理想性能的炸药，可获得最小破坏的低密度炸药，尽量消除故障的稳定性炸药，露天和地下矿用的散装炸药，精确的起爆系统和灵活的起爆系统．本文概述这些进展，重点探讨每种进展的合理性。
Explosion using explosives has always been the main means of rock fragmentation. Despite the considerable efforts made in the area of non-explosive explosives, it is still safe to foresee that explosives will continue to be exploded in the future. In the past few years, the explosives industry has significantly matured, and users have also raised the demand for explosives performance and quality control. Explosive properties can be adjusted to suit a given blasting environment, and instrumentation can provide useful information to optimize blasting. Explosion Probation has been developed to control the impact on the rock mass energy and swelling ratio of the controlled non-ideal performance of the explosives, to obtain the smallest destruction of low-density explosives, as far as possible to eliminate the stability of the fault explosives, open-air and underground Mine explosives in bulk, accurate detonation system and flexible detonation system. This article outlines these developments, focusing on the rationale for each of these developments.
