我队自制回转电钻是在探矿平巷任务紧迫,专用机掘设备未能及时到队的情况下自行设计制作的。通过多年的生产实践,证明这一机具在中硬岩石中具有钻眼效率高、操作方便、加工容易、成本低廉、牢固耐用等优点,有一定的实用意义。特别是目前经济调整时期,重型坑探任务不大,少量平巷工作如按全套机掘设备进行设计,势必因掘进任务小,机械效能不能充分发挥,影响经济效果,如以手工作业不仅劳动强度大,且施工进度慢,影响地质工作的顺利开展。据此,如能采用自制回转电钻进行钻眼爆破,则可取得较好的经济效果 Our team made the rotary drill is in the prospecting Pingxiang urgent task, dedicated machine digging equipment failed to team to design and manufacture of their own. Through years of production practice, this machine has proved to be of practical significance in medium-hard rock with the advantages of high drilling efficiency, easy operation, easy processing, low cost, and firmness and durability. Especially in the current period of economic adjustment, heavy pit exploration mission is not large, a small amount of laneway work, such as a full set of machine digging equipment design, is bound to lead to the task of small, mechanical efficiency can not give full play to affect economic results, such as manual work not only labor intensity Large, and the construction progress is slow, affecting the smooth development of geological work. Accordingly, if the use of self-rotating rotary drill drill blasting, you can get better economic results
