河南省鄭煤集團超化3#礦井初步設計
摘  要
 本設計是對河南省鄭煤集團超化3#礦井二1煤層所作的初步設計。超化礦自然地質條件中等，二1煤層屬厚煤層，平均厚度10.0m。礦井瓦斯涌出量大，為煤與瓦斯突出礦井，煤塵具有爆炸危險性，煤層為不易自燃煤層，礦井涌水量較大。設計采用立井二水平上下山式開拓，采區式準備，綜合機械化放頂煤開采。主要對礦井開拓方式、準備方式和采煤方法進行了初步設計，對礦井運輸、提升、通風、排水等生產系統進行了描述和設備選型計算。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。

Preliminary Mine Design for No.3of Zhengzhou Mining Group in Henan Province
ABSTRACT
 This preliminary mine design is for No.3 of Zhengzhou Mining Group in Henan Province. The design is based upon No.3 the actual nature term and geology at present, whose average thickness is ten meters high, methane concentration is high seam is prone to self-ignite and whose capacity is medium. The design adopts the vertical shaft method with two-level up to expand and down to expand the mine plus fully mechanized mining method for the whole seam district for preparation. The design mainly details upon the development pattern, preparation pattern and mining method and transportation, drainage, hoisting, ventilation and water discharge are also described and calculated for production system. 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.
