摘要
针对鲍店煤矿锚喷支护巷道中存在的问题，根据影响巷道稳定的８ 个因素，将巷道分为四个类型，且通过工程测试分析了各类巷道的变形特征，提出了锚喷支护巷道支护参数的设计方法，并应用新型拉拔锚杆进行了井下试验，取得了较好的技术经济效果。
In the light of the exising problems of the roadways supported by bolting and shotcreting in Baodian Coalmine, the roadways were divided into four types according to the eight factors which affect the roadway's stability, and an approach was suggested for designing the supporting parameters of roadways supported by bolting and shotcreting through the analysis of various roadway's deformation characters by means of engineering tests, the underground test was carried out with a new type of drawing bolts and the fairly good technical economic results were achieved.
