摘　　要：绿色矿山是砂石行业的发展趋势,针对石材开采过程中粉矿率和爆破危害效应方面存在的问题,一方面通过分析粉矿的来源,从爆破环节和挖运环节两个方面控制爆破过粉和泥粉混入,进而达到降低粉矿率的目的;另一方面通过采取逐孔爆破、洒水降尘、紧密联系群众等措施,使爆破危害效应得到了有效控制,促进了企地关系和谐发展。Green mine is the development trend of sand and stone industry. In view of the problems existing in the silty ore rate and the harmful effect of blasting in the stone mining process,on the one hand,through analyzing the origin of silty ore,control the mixing of blasting over powder and mud powder from the aspects of blasting link and digging and transportation link,so as to reduce the silty ore rate. On the other hand,by taking measures such as hole blasting,sprinkling water and dust,and closely contacting with the masses,the harmful effect of blasting is effectively controlled and the harmonious development of the relationship between enterprises and land is promoted.
