目前,我国煤炭产量80%左右是放炮落煤,爆破条件直接影响爆破效果和爆破安全。爆破过程中炸药为引火源引爆瓦斯、煤尘已占瓦斯、煤尘爆炸事故的第一位,这除与炸药本身对瓦斯、煤尘的安全性有直接关系外,爆破条件不当也是重要原因之一。为搞好爆破安全,在狠抓研制、生产、使用安全度高的炸药的同时,还要创造科学的爆破条件,这在当前煤矿 At present, about 80% of the coal output in our country is aiming to demolish the coal. The blasting conditions directly affect the blasting effect and blasting safety. Explosives in the process of explosions detonate gas for the ignition source, coal dust has accounted for gas, coal dust explosion accident first, which in addition to the explosives itself on gas, coal dust safety is directly related to improper blasting is also an important reason one. To do a good job blasting safety, pay close attention to research, production, use of high explosives safety, but also to create a scientific blasting conditions, which in the current coal mines
