摘  要

 本設計礦井的井田面積為29.96平方千米，年產量300萬噸。井田內煤層賦存比較穩定，煤層傾角，平均3°，煤層厚度平均8.0m。井田范圍內整體地質條件比較簡單，斷層較發育，但均是小斷層。礦井瓦斯含量較高，為高瓦斯礦井，礦井涌水量不大。根據實際的地質資料情況進行井田開拓和準備方式的初步設計，該礦井決定采用雙斜井兩水平上下山開采，采用帶區式開拓方式。設計采用綜合機械化放頂煤回采工藝，傾斜長壁采煤法，用全部跨落法處理采空區，并對礦井運輸、提升、排水和通風等各個生產系統的設備選型計算，以及對礦井安全技術措施和環境保護提出要求，完成了整個礦井的初步設計。礦井全部實現機械化，采用先進技術和借鑒已實現高產高效現代化礦井的經驗，實現一礦一面高產高效礦井從而達到良好的經濟效益和社會效益。

Abstract

 These designed allotment area for 29.96 square kilometers，Yearly Output three-hundred trillion. Allotment intrinsically ocurrence of coal seam compare stabilize，coal seam pitch is under fifteen acid，average coal seam pitch is three acid.Coal seam thick is 8.0m，integrally nature condition compare simplicity，at allotment scope east normalizing function of the stomach and pleen center equal have got dislocation upgrowth. Both methane and carbon dioxide content relatively do not high, and neither do inflow of water no large either. On the basis of Preliminary Design，said shaft opt in adopt three vertical shaft fluctuate mountain exploitation，coal seam grouping band region fluctuate mountain co- disposal 'mode of opening，design adopt comprehensive mechanization full-seam mining stopper art，incline longwall method，treat goaf with whole straddle alight law from actual geologic information instance proceed allotment exploit and stand-by mode. The Preliminary Design of the both both combine versus mine haul, shaft exaltation, shaft drain and ventilation of mines isopuant systemic equipment lectotype count，as well as versus shaft technical safety measures and environmental protection claim，complete wholly shaft. Both shaft whole realize mechanization，adopt advanced techniques and use for reference afterwards realize high yield highly active modernization shaft 'experience，realize one mine not both high yield highly active shaft thereby run up to favorable economic benefit and social benefit.
