摘要
随着煤炭开采技术的发展及锚杆支护技术的推广应用,宽煤柱已逐步被窄煤柱或无煤柱沿空掘巷所取代。文章主要介绍了安泰煤矿无煤柱沿空掘巷时,制作人造帮、合理选择支护方式及参数、加强管理和观测等实践经验,取得了良好的技术经济效益。
In order to ensure the safety of the mine,long-term since,most of underground mine construction in mining face more than a certain width between a of coal pillar,leave set of coal pillar can effectively prevent the production or ready to face and adjacent goaf fully or air leakage and cause the spontaneous combustion in the mined-out area,while taking into account the working pressure,so although appeared to safety in mine to protect the role but it caused the coal waste of resources,as the coal mining technology and the development of anchor supporting technology,the popularization and application of the coal pillar width has gradually be narrow coal pillars or no coal pillars along goaf and replaced lane.
