竖井延深使用ΠР—27型手持式凿岩机凿浅眼,是最繁重的掘凿作业之一。此外,手持式浅眼凿岩时,往往不能保证竖井掌子面的空气粉尘达到卫生标准,同时凿岩振动也损害工人的健康。 为了浅孔凿岩机械化,从而减轻劳动消耗,在苏联顿巴斯中心区的阿尔焦莫夫斯基煤炭公司加里宁矿井№3井筒延深中,使用了库兹涅茨克矿井建设科研所研制的СМБу—4M型风动凿岩设备。这种设备是在中心 Deepening shaft ΠР-27 type hand-held rock drill chisel shallow, is one of the most heavy digging operation. In addition, hand-held shallow-hole rock drills often fail to ensure that the airborne dust on the face of the shaft meets the hygiene standards and that rock-blasting also damages workers’ health. In order to shallow hole drilling mechanization, thereby reducing labor consumption, in the central area of ​​Burundi, Moscow, Suzuki Alginovsky coal company Kalinin Mine № 3 wellbore extension, the use of the Kuznetsk mine construction research institute СМБу-4M-type pneumatic rock drilling equipment. This equipment is in the center
