河南省郑煤集团超化3#矿井初步设计

摘 要

本设计是对河南省郑煤集团超化3#矿井二1煤层所作的初步设计。超化矿自然地质条件中等，二1煤层属厚煤层，平均厚度10.0m。矿井瓦斯涌出量大，为煤与瓦斯突出矿井，煤尘具有爆炸危险性，煤层为不易自燃煤层，矿井涌水量较大。设计采用立井二水平上下山式开拓，采区式准备，综合机械化放顶煤开采。主要对矿井开拓方式、准备方式和采煤方法进行了初步设计，对矿井运输、提升、通风、排水等生产系统进行了描述和设备选型计算。矿井全部实现机械化，采用先进技术和借鉴已实现高产高效现代化矿井的经验，实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。

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.

Keywords:Coal mine Preliminary mine design High-gas protrusion Vertical shaft for development
