锚杆支护作为一种积极主动的支护技术,在我国乃至世界范围的巷道支护中,所占的比例越来越大。其简便快捷的施工,简单的施工方法,良好的支护效果,较轻的劳动强度,较好的适应能力,已经得到了广泛的认可。且随着锚杆支护器具的发展,在井工采矿实践中,使其得到了更为广泛的应用。该文笔者结合现场实践的基础上,通过对锚杆支护失效原因的分析,提出了相应的应对措施,对于提高锚杆支护效果有积极的借鉴意义。
As a kind of proactive support technology, bolt support takes more and more proportion in roadway support in our country and even in the world. Its simple and quick construction, simple construction method, good support effect, light labor intensity, better adaptability, has been widely recognized. And with the development of bolt supporting equipment, it has been widely used in the field of mining. Based on the field practice, the author of the paper analyzes the causes of the failure of bolt support and puts forward the corresponding countermeasures, which has positive reference for improving the effect of bolt support.
