随着生产技术的发展,1982年我矿决定采用控制爆破在露天矿实现一次成坡代替大量的民工修坡。当时国内市场上提供的小型潜孔钻机种类较少,已有的几种钻机大都没有机械接卸钻杆装置,多数也没有司机室,不适合我矿的使用。在这种情况下,我们决定利用已报废的国产YQ150型钻机的底盘改装成能适应我矿需要的潜孔钻机。经过二年多的工作于1985年改装完毕(我们将其命名为GX-100型露天多向潜孔钻机),1986年4月至7月在我矿露天采场进行了工业试验,试验结果表明能满足我矿生产的需要,现已正式投入生产。 With the development of production technology, in 1982 our mine decided to use controlled blasting to achieve a slope in the open pit instead of a large number of migrant workers to repair slopes. At that time, there were few types of small-scale DTH drilling rigs available on the domestic market. Most of the existing drilling rigs did not have mechanical drilling and unloading drill rods. Most of them did not have a driver’s cab and were not suitable for the use of mines. In this case, we decided to use the chassis of the domestically-manufactured YQ150 drilling rig to be converted into a down-hole drilling rig that can meet the needs of our mine. After more than two years of work, the conversion was completed in 1985 (we named it the GX-100 type open-air multi-decked downhole drilling rig). From April to July 1986, an industrial test was conducted in the open pit of our mine. The test results show that To meet the needs of our mine production, it is now officially put into production.
