摘要
以某煤矿其中一个工作面为研究对象,在建立其沿空留巷力学模型的基础上,根据实际生产情况制定了沿空留巷巷内及巷旁的支护方案,并根据支护强度要求选择了合适的巷旁填充材料。经实践表明,所提出的沿空留巷支护方案取得了良好的留巷效果,为采煤工作面的安全生产奠定了基础。
Taking one of the working faces of a coal mine as the research object,on the basis of establishing the mechanical model of the roadway along the goaf,and according to the actual production situation,the supporting scheme of the roadway along the goaf and the side of the roadway is worked out.According to the requirements of support strength,the suitable filling material next to roadway is selected.The practice shows that the proposed roadway retaining technology has achieved good roadway retention effect,which lays a foundation for the safety production of coal mining face.
