摘　　要：余吾煤矿地面村庄及建(构)筑物较多,压煤量较大,导致现有生产采区可采资源量不足,采区接替趋于紧张,亟需对南六采区进行规划设计与开拓部署。南六采区巷道垂直于南翼大巷布置,担负采区通风、运输和排水等任务,设计提出了3个巷道布置方案。从井巷投资、瓦斯抽采、井下发生灾变时人员逃生、硐室布置等方面,对各方案作了分析比较,最终确定了最优方案,并被业主采纳。该方案可降低井巷工程量及投资,缩短工期,有利于布置采区硐室及发生灾变时人员逃生;对于类似条件矿井采区巷道布置,具有借鉴意义。There were many villages and buildings on the surface ground of Yuwu Mine.There were many coal reserves under the villages and buildings.Thus the mineable coal reserves in the available production mining block were insufficient,the mining block alternation was in tension and a planning design and the development deployment were required and conducted to the South No.6 Mining Block.The mine roadway in the South No.6 Mining Block was perpendicular to the layout of the mine south wing roadway and would undertake the ventilation,transportation,mine water drainage and other missions in the mining block.The design provided three roadway layout plans.From the mine roadway investment,mine gas drainage,personnel escape when disaster occurred in the underground mine,chamber layout and others,an analysis and comparison was conducted on each plan and an optimal plan was finally determined and was accepted by the owner.The plan could reduce the work quantity and investment of the mine roadway,could cut down the construction period and would be favorable to the layout of the chambers in the mining block and to the personnel escape when a disaster occurred.The plan could provide the reference significances to the roadway layout in the mining block of the mine with the similar condition.
