摘　　要：对目前煤矿井下综采设备螺栓防护措施存在的问题进行改进,利用热缩管高温收缩、绝缘防腐蚀的特性和聚氨酯的高强度和弹性,对螺栓进行防护,最大限度减小腐蚀,降低维修成本,提高设备的开机率,具有实用价值和推广意义。Improving the existing problems of bolt protection measures for compound mining equipment in coal mine. Protect the bolts by using the high temperature shrinkage,the insulation anticorrosion characteristic of heat shrink tube and the high strength and elasticity of polyurethane. It can minimize the corrosion, reduce the maintenance cost and increase the start-up rate of the equipment. It has the practical value and the popularization significance.
