【正文】 of . It is developed with vertical shaft, double mining level, risedip, gathering mian roadway, and the first mining level of 630m. The coal mining method is longwall mining to the dip or the rise, fullymechanized coal mining technology. For the choice of the industry square position, it must be advantageous to the mine development and preparation, to the construction and the industry location arrangement.Belt conveyor has the advantage of strong continuous transportation, so it is the best choice for the coal transportion. The auxiliary transportion is undertaked by railway, with the normal mine car. The transportion hauling equipment is always the mine lootive, but this mine is a gassy 畢業(yè)設(shè)計(jì)總說明IVmine, so the lootive must be the storage battery lootive.According the known conditions, referring to the atlas of shaft section, the shaft sections are determined. The main shaft’s radius is , equipped with double 12t skip, the auxiliary shaft, with double floorfour car wide narrow cage, and the ventilating shaft, with ladder roadway and pipeline roadway.The length of the first working face is 180m. As the 32 coal seam’s occurrence and stability is very well, with angle of coal seam flat. Shearer with the central oblique way into the coal wall cut the coal, with the former roller cutting the top coal while the latter cutting the drum coal. 6 knifes is plished every day, that is to say, 2 knifes every class. For the labor anization in coal face, machinefollowing is adopted. To ensure the timely relay of the strip, gobside entry retaining is adopted. That is to say, the inclined railroadway or haulageway of the existing strip, will be retained for the following one. For this mine, the ventilation is radial ventilation of doublewing, to achieve the purpose of controlling the gas accumulation, and safety.Key words: Vertical shaft。 double level。 Longwall mining to the dip or the rise。 Fullymechanized coal mining technology。 Radial ventilation of doublewing目錄I目錄1 礦區(qū)概述及井田地質(zhì)特征 ..............................................................................................................................................1 礦區(qū)概況 ....................................................................................................................................................................1 礦區(qū)地理位置及地形特點(diǎn) ................................................................................................................................1 礦區(qū)氣候條件 ....................................................................................................................................................1 礦區(qū)的水文情況 .................................................................................................................................................1 井田地質(zhì)特征 ...........................................................................................................................................................3 煤層特征 ...................................................................................................................................................................3 瓦斯，煤塵及自燃 ....................................................................................................................................................42 井田的境界和儲(chǔ)量 ..........................................................................................................................................................7 井田的境界 ...............................................................................................................................................................7 井田劃分的依據(jù) .................................................................................................................................................7 井田的范圍 ........................................................................................................................................................7 開采界限 ............................................................................................................................................................7 井田尺寸 ............................................................................................................................................................8 井田的工業(yè)儲(chǔ)量 .......................................................................................................................................................8 儲(chǔ)量計(jì)算基礎(chǔ) ....................................................................................................................................................8 保護(hù)煤柱儲(chǔ)量及可采儲(chǔ)量的計(jì)算 ....................................................................................................................93 礦井工作制度和設(shè)計(jì)生產(chǎn)能力 ....................................................................................................................................13 礦井工作制度 .........................................................................................................................................................13 循環(huán)作業(yè)方式 ..................................................................................................................................................13 綜采工作面循環(huán)作業(yè) ......................................................................................................................................13 礦井工作制度的確定 ......................................................................................................................................14 礦井設(shè)計(jì)生產(chǎn)能力及服務(wù)年限 .............................................................................................................................14 礦井設(shè)計(jì)生產(chǎn)能力的影響因素 ......................................................................................................................14 確定依據(jù) ........................................................................................................................................................
