综采工作面快速扩通道优化设计在高山煤矿的研究与应用

Research and application of optimization design of rapid expansion of channel in fully mechanized working face in gaoshan coal mine

高山煤矿1901综采工作面支架因架型体积大、吨位重,回撤支护技术研究显得尤为重要。为了加快1901采煤工作面的安全回撤速度,提高矿井的产量和效益,通过三个方案的对比,使高山煤矿在工作面回撤扩通道设计技术上更加成熟,实现了安全施工,降低了劳动成本。

The recovery technology is particularly important,because of the supporting with large volume, and weight tonnage in 1901 fully mechanized working face. In order to speed up the 1901 coal mining working face safety retraction speed, improve the yield and benefit of the mine, by comparing the three schemes, selected the reasonable recovery plan, implemented the safety construction, and reduced labor costs.
