不规则综放工作面 开采技术创新与实践 作者姓名： 作者班级： 指导教师： 不规则综放工作面开采技术创新与实践 2011级 采矿工程 ××× 摘要：随着煤炭开采量的增加和开采范围的扩大，受煤炭赋存条件和地质条件的限制，一般的综采（综放）工作面的很难规则布置，即使布置也是小范围的规则配合“刀把”进行布置，同时一部分受断层影响的煤炭得不到有效的开采，如果不采，丢失煤炭比较可惜，如果进行复采，势必要重新布置巷道，面临老空区压力等等不利因素影响，开采难度极大。 针对这种实际情况，为提高井下煤炭资源回收，付村煤业有限公司在多个紧贴断层布置的工作面回采过程中积极探索不规则工作面开采技术，在回采过程中成功运用了边推采边安装支架和溜槽、边推边撤出支架和溜槽的开采技术，为配合新的开采技术应用，在每个回采环节中多点创新，并取得了圆满成功，通过实施不规则工作面技术开采不仅创造了巨大的经济效益，也为以后综放工作面不规则回采积累了宝贵经验。 关键词：不规则 开采技术 边推边安装 边推边撤除 效益 经验 Summary：With the development of coal mining quantity increase and expand the scope of mining, by coal occurrence conditions and geological conditions, the general mining caving working face is difficult to rule arrangement, even if the layout the small scope rules with hilt layout, also part of the broken layer of coal is not effectively mining, if there is not a loss of coal, unfortunately, if repeated mining, is bound to roadway layout, the face of adverse factors of old goaf pressure effect, it is difficult to be exploited. In the face of this situation，to improve the recovery of underground coal resources, to pay the village close to the fault Coal Co., decorated in a number of working surface of the process of actively exploring irregular Mining technology, successfully used in the extraction process, pushing the mining side of the mounting bracket and the chute , pushing the side of the withdrawal of support and troughs mining technology, in line with the new mining technology, in every part of the more innovative mining, and achieved great success through the implementation of irregular face mining technology has not only created enormous economic benefits, but also for recovery after irregular caving face has accumulated valuable experience。 Keywords：Irregular；Mining technology；Pushing the edge installation：Pushing the edge withdrawal；Benefit；Experience 概述 枣庄矿业集团付村煤业有限公司东四采区的3上401、3上411、3上403改造Ⅱ面、3上403改造Ⅰ面都是材巷紧贴断层布置的不
