岩金矿露天开采—霹天矿中深孔松动控制爆破的应用 洋鸡山金矿在露天开采中一直使用护壶剂爆法。由于该法爆破产生地震波、冲击波和飞石,严重威胁和危害周边的农田耕作和民房安全,1989年6月,该矿决定和科研院所共同进行中深孔松动控制爆破试验研究。 试验研究以现场为主,首先从理论上探讨爆破安全距离入手,并作矿、岩可爆性测定和炸药单耗q值测定,然后进行现场爆破参数试验研究。爆破参数以孔径为主,由小至大逐步试验。 Rock gold mining open pit mine - Application of controlled blasting in deep hole loose 洋鸡山金矿在露天开采中一直使用护壶剂爆法。由于该法爆破产生地震波、冲击波和飞石,严重威胁和危害周边的农田耕作和民房安全,1989年6月,该矿决定和科研院所共同进行中深孔松动控制爆破试验研究。 In the open pit mining, the use of the pot - proof explosion method has been used in the. Due to seismic wave, shock wave and the method of blasting slungshot, safety, serious threat and harm the surrounding farmland and houses in June 1989, the mine decision and scientific research institutes jointly conducted experimental study on deep hole loose blasting control. 试验研究以现场为主,首先从理论上探讨爆破安全距离入手,并作矿、岩可爆性测定和炸药单耗q值测定,然后进行现场爆破参数试验研究。爆破参数以孔径为主,由小至大逐步试验。 Experimental study on the field, starting with the theory of blasting safety distance of ore and rock blastability, determination of the consumption of explosives and determination of Q value, and then the experimental study of blasting parameters in the field. The blasting parameters to the aperture, from small to large step test.
