摘要
利用扇形中深孔进行井下采场的光面爆破 ,可达到控制采场地压、维护空场的稳定和降低损失率、贫化率的目的。该技术将光面爆破的布孔方式发展到扇形中深孔 ,把光面爆破技术应用到新领域 ,经试验证明是可行的。它的成功经验对其它矿山具有一定的参考借鉴作用 ,值得推广。
Applying smooth blasting of fan shaped medium length holes in underground mining.it can control underground pressure,safeguard the stability of stope empty and reduce ore loss rate and dilution rate.This technology has developed the drilling way of smooth blasting into the fan shaped medium length holes,as a result,the smooth blasting can be used in a new field.It proved from experiment that it is feasible.So this successful experience is worthy to be popularized.
