摘 要:在矿井掘进过程中,巷道顶板发生安全事故占有非常大的比重,因此在掘进工作中,加强对巷道顶板稳定性研究十分必要,这种做法能够有效减少采矿中出现事故的概率,保证矿井采掘过程中人员的安全,为矿企带来更大的经济效益。国内外将矿山巷道顶板稳定性进行分类正由单因素定性分类向多因素、多定量、多指标的综合模式发展。虽然分类方法及侧重点有所不同,但是其最终目的都是反映矿山巷道结构的复杂性,为矿山巷道支护参数及稳定性评价提供理论依据。In the process of mine excavation,the safety accidents of roadway roof occupy a very large proportion,so it is necessary to strengthen the study of roadway roof stability in the excavation work.This method can effectively reduce the probability of accidents in mining,ensure the safety of personnel in the process of mine excavation,and bring greater economic benefits to mining enterprises.Economic benefits.The classification of mine roadway roof stability at home and abroad is developing from single factor qualitative classification to multi-factor,multi-quantitative and multi-index comprehensive model.Although the classification methods and emphases are different,the ultimate purpose is to reflect the complexity of mine roadway structure and provide theoretical basis for the evaluation of support parameters and stability of mine roadway.
