通过对各参数的计算并与浅孔爆破相应参数的比较,说明中深孔爆破方式在技术和经济上均优于浅孔爆破方式,并从其可操作性及安全距离两方面进行计算论证。矿山生产实践表明,采用中深孔爆破方式爆破能够减少爆破次数,为矿山生产赢得时间的同时提高生产的安全性,降低采矿成本,提高矿山的经济效益。 The comparison between the parameters and the corresponding parameters of shallow hole blasting shows that the middle and deep hole blasting methods are superior to shallow hole blasting technically and economically in terms of both operability and safety distance. Practice of mine production shows that blasting with medium-deep borehole blasting can reduce the number of blasting, gain time for mine production, improve safety of production, reduce mining cost and increase economic benefit of mine.
