特殊环境下采煤工作面设计的优化和选择

The Optimal Design and Selection of Mining Work Face under Particular Circumstance

济宁二号煤矿隶属于兖州煤业股份有限公司,井田面积90km2,地质储量8.55亿t,可采储量3.47亿t。矿井井下地质条件复杂,煤层赋存变化大,断层多,工作面巷道布置易受影响。本文以济宁二号煤矿93下03工作面顺槽布置方式为实例,探讨如何在综采工作面周围地质条件复杂的状况下优化巷道布置设计。

Jining NO.2 coal mine is belong to Yankuang group co.,LTD,whose area of field is about 90km2,geological reserves about 0.85 billion tones,and exploitable reserves about 0.347 billion tones.However,the underground geological conditions of coal mine is extraordinary complex,and ocurrence of coal seam changing largely,also with many fault,which can easily influence the mining work faces＇ arrangement.This thesis take arrangement of gate roadway of the 93 rd beneath 03 rd work face as example,discussing how to design and optimize roadway under the circumstance of the geological conditions surround the fully mechanized work face is very complex.
