我矿在全面推行了风腿子,实行单人多机凿岩的基础上,为进一步寻求巷道的快速掘进方法,我们进行了小直径凿岩试验工作。通过试验证明在巷道掘进中,使用小直径钎头凿岩是可以提高工效、減少材料消耗、降低成本与减经劳动劳动强度的,也是加快巷道掘进速度的重要技术改进措施之一。一、试验的技术条件试验中使用OM—506机两台,风腿子两个,钎头为BK—15一字形,直径34～36公厘,刃角110°,钎杆为直径24公厘的六角钢钎,长为0.9～1.7公尺,岩
Based on the full implementation of Fengzizi and the implementation of single-person multi-machine rock drilling, in order to further seek the rapid excavation method of mine roadway, we carried out small-diameter rock drilling test work. Experiments prove that the use of small diameter drill bit rock drilling in roadway excavation can improve work efficiency, reduce material consumption, reduce costs and reduce labor intensity, and it is also one of the important technical improvement measures to speed up roadway excavation. First, the technical conditions of the test OM-506 machine used in the test two, two wind-legged, BK-15 bits for the first drill, a diameter of 34 to 36 mm, angle of 110 °, drill rod diameter of 24 mm Hexagonal brazing, length of 0.9 to 1.7 meters, rock
