目前，在我国中小型矿山仍在普遍使用YQ-100和YQ-100B型潜孔钻机，该机体积小，重量轻，结构紧凑，造价低廉，操作方便。该机存在的主要问题是工作参数不尽合理，与之配套的旁侧排气冲击器早期破坏寿命短，凿岩效率低。针对YQ-100型钻机的缺点，我矿自1991年开始研究开发SQZ-10
At present, YQ-100 and YQ-100B DTH drilling rigs are still commonly used in small and medium-sized mines in our country. The aircraft is small in size, light in weight, compact in structure, low in cost and convenient in operation. The main problem of the aircraft is the working parameters are not reasonable, with the accompanying side exhaust impactor early destruction of short life expectancy, rock drilling efficiency is low. For the shortcomings of YQ-100 drilling rig, mine mine research and development SQZ-10 since 1991
