天安煤矿井田开拓方案的可行性分析

The Feasibility Analysis on Tianan Coal Mine’s Development Plan

通过对天安煤矿井田开拓方案的可行性分析,得出结论:该井田赋存2号、5号两层可采煤层,首采区布置在5号煤层内。首采区位于井田东南部504采区内,首采区内以111b级储量为主。全井田可划分为5个采区,分别为504、505、506、201、202采区,矿井采用分列式通风,主斜井、副斜井进风,回风斜井回风。

The feasibility analysis on Tianan Coal Mine’s development plan draws the conclusion that the occurrence of this coal mine includes two minable seams of No.2 coal seam and No.5 coal seam,the first mining area is arranged in No.5 coal seam;the first mining area,giving priority to 111 b reserves,is located in 504 mining area in southeast of the coal mine;the whole coal mine can be divided into five mining areas of,respectively,504,505,506,201 and 202 mining area,and the coal mine adopts the march-past ventilation,the main slope shaft and auxiliary slope shaft for intaking air,and return air slope shaft for returning air.
