摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为酸刺沟煤矿3.0Mt/a新井设计。酸刺沟煤矿属于内蒙古伊泰集团,位于内蒙古自治区东胜煤田内。井田南北走向长约8.9km,东西倾向长约6.5km,总面积为58.74km2。煤层平均倾角2,为近水平煤层,埋藏浅,埋深平均215m,其中表土层为81m,设计所采煤层为4号煤,平均厚度3.82m。矿井工业储量329.359Mt,可采储量251.367Mt,服务年限64.5a。矿井开拓方式为斜井单水平开拓,主井、副井为斜井,风井为立井,在井底沿东西向布置煤层大巷开拓一、二盘区,在北部布置东西向煤层大巷开拓三盘区,主斜井倾角13,全长991m,装备带式输送机,副斜井倾角6,全长1922m,装备无轨胶轮车;风井净直径5.5m,井筒深度301m,装备玻璃钢梯子间。移交生产时,在4号煤布置一个综采工作面,一个连采掘进工作面和一个普通掘进工作面,采掘比为1:2。连续采煤机还能进行煤柱回收和回撤巷道煤柱回收。工作面长度为240m,年推进度为2805m。日产量为9091t,通风方式为中央分列式。矿井主运输采用带式输送机,煤从采掘工作面到地面实现连续运输;矿井辅助运输采用无轨胶轮车,人员、材料、设备可以实现从地面到工作面附近直达运输。专题部分题目:神东矿区浅埋采场溃沙分析及控制机理研究翻译部分题目:A Method for The Design of Longwall Gateroad Roof Support ,对应中文翻译为:长壁工作面顺槽顶板支护设计关键词:浅埋煤层 ;近水平煤层 ;盘区布置 ;斜井单水平开拓 ;煤层大巷 ;双巷掘进 ;连续采煤机 ;无轨胶轮车 ;中央分列式 ; 溃沙 ABSTRACTThis design includes of three parts: the general part,special part and translated part.The general part is a new design of Suancigou coal mine,which produces 3Mt per year.It belongs to Yitai group of Inner Mongolia and it lines in Dongsheng coalfield.The length of the north-south direction of the coalfield is 8.9km and the east-west direction length is 6.5 km,so its area is 58.74km2.The main coal seam which I design is No.4 coal seam ,which dip angle is 2 degree and its depth is 215m,3.82m for its thickness.The proved reserves are 329.359 Mt and the recoverable reserves are 251.367Mt,and it can work 64.5 years. The way to open up the mine is the shaft single horizontal development.The main shaft and the auxiliary shaft are inclined ones,but the air shaft is not.We arrange the roadway-in-seam along the east-west direction to open up the No.1 and No.2 panel,then in the north area,we arrange another east-west direction roadway-in-seam to open up the No.3 panel.The dip degree of the main shaft is 13 and auxiliary one is 6.Thelength of the main shaft is 991m and the auxiliary one is 1922m.The diameter of the air shaft is 5.5m and its length is 301m.When produced,we arranged a working ,a continuous miner heading face and a general heading face.So the ratio of the mining and driving is 1:2.The length of the working face is 240m and its continuous promoting length is 2805m.It produces 9091t every day.The way of the major transport is belt conveyor and the auxiliary transport is rubber tire vehicle.They can realize continuous transport.My topics of special subject parts is The Analysis of The Shallow Seam Blown Sand and the Study on its Control Mechanism in Sendong Coalfield.My translation part is A Method for The Design of Longwall Gateroad Roof Support.Keywords:Shallow seam ; Nearly horizontal seam ; Panel lavout ; Single-level development with inclined shaft ; Roadway-in-seam ; Dual roadway ; Continuous miner ; Rubbr tire vehicle ; Central-past ; Blown sand 2
