似刀把状不规则综采工作面开采实践研究

Practice Research on Mining at Knife-like Irregular Fully Mechanized Working Face Mining

本着降低煤损率,提高矿井开采年限的目的,将21110工作面设计为似刀把状不规则工作面。通过对该不规则工作面实际分析,掌握了回采过程中遇到的关键性问题,结合多方面因素制定了该工作面开采方案。该工作面的开采是对不规则工作面的一次成功探索,为开采不规则工作面积累了丰富的经验,同时也为其他矿井类似工作面的开采提供了参考。

21110 working face is designed as a knife -like irregular one in the purpose of coal loss rate reduction and mining life improvement .By actual analysis of the irregular working surface ,the authors have worked out a successful mining scheme in consideration of the key problems encountered during the mining process ,which can provide a reference for other similar working face .
