摘要
介绍了一种实用新型专利矿用支护锚杆使用和改进过程,该锚杆在几乎不增加耗材的前提下,提高了杆体结构强度和支护效果,该锚杆的推广将促进节能减排工作和煤矿的安全生产。
This paper introduces the process of the usage and improvement of a mine-used supporting anchor-bolt patented for utility model. On the premise of increasing less material cost, the structural strength of rod body and the supporting effects of the anchor bolt are improved. The popularization of this improved anchor bolt will promote energy saving, emission reduction and the safety production in a colliery.
