摘要
通过分析锚杆预紧力对提高巷道支护效果方面的作用,指出巷道的初期变形可以通过提高锚杆的预紧力加以控制,论述了锚杆预紧力的计算方法,并结合工艺设备现状给出了提高锚杆预紧力的技术措施。而骆驼山煤矿巷道支护中的工程实践,进一步验证了该理论的运用结果。
Through the analysis of bolt pretightening force to improve roadway support effect,the roadway initial deformation can be controlled by improving bolt pretightening force,the calculation method of bolt pretightening force was discussed,and the technical measures of improving bolt pretightening force were given.The validity of the theory was verified by the roadway support engineering practice in Luotuoshan coal mine.
