蒋庄煤矿矿井延伸设计.doc

摘要
本文详细讲述了蒋庄煤矿的井田地质及煤层特征,井田开拓方式,以及矿井的主要生产系统,并对矿井延深的必要性进行深入的分析。
在二水平开拓中,首先确定二水平开采范围与生产能力,然后在开拓准备中,根据矿井已有一水平开拓并结合二水平煤层赋存特点及地质条件,设计了两个二水平延深方案,分别是:副井直接延深、主井暗斜井延深;主副井均采用暗斜井延深。通过技术经济比较,最终确定选用主副井均暗斜井延深。接着本文对井筒和暗斜井上下车场及硐室进行了设计,针对二水平情况布置首采区,位于斜井下部车场附近,即1603采区。选择合适的通风方式与通风系统,最后完成对通风系统的设计。

ABSTRACT
This article in detail narrated the Jiangzhuang coal mine field geology and the coal bed characteristic, the well field development way, as well as the mine pit main production system, and extends the deep necessity to the mine pit to carry on the thorough analysis.
In two level developments, first determined two level mining scope and productivity, then in the development preparation, had a level according to the mine pit to develop and unify two horizontal coal bed taxes to save the characteristic and the geological condition, designed two two levels to extend the deep plan, respectively was: The vice-well extends deeply, the main well directly uses the inside slope to extend the depth; The primary and secondary well directly uses the inside slope to extend the depth. Through the technical parison, finally determined selects the primary and secondary well inside slope to extend the depth. Then this article the cart yard and mountain cave the room has carried on the design to about the well chamber and the inside slope, design the first mining area near the below paking lot .1603 mining area. chooses the appropriate well ventilated way and the ventilation system, pletes to the transportation system design.
Keywords:The inside slope extends the depth,Extends the deep design,Mining area-design,Ventilation system
