松软煤层锚杆支护技术的研究及其应用实例

s the mine been continued to extend to the deep，As Roadway damage caused by the problem of pressure，which has bring a lot of trouble for Supporting roadway，the rock roof is Soft and affected by mining, roof has broken,to maintain it become even more difficult, Therefore, This paper analyzes the principle and method of bolting, and according to actual situation, Systematically analysis of deep coal mines in Shandong an occurrence of the geological features of surrounding rock,andControl factors such as difficulty and stress, Analysis the conditions of coal support, Application of coal mine roadway bolt strength reinforcement theory, use the high-strength steel bolt support technology, successfully resolved the problem of difficult to support in Weak Seam, The successful application of the bolt Support Technology in the Coal Mine, Provide Valuable experience for the experience of other roadway For other roadway.
