煤柱综放工作面过旧巷回采技术应用

Coal Extraction Technology Application in Coal Pillar Fully Mechanized Caving Face Crossing Old Roadway

针对兰花集团莒山煤矿煤柱综采放顶煤回收工作面回采过程中频繁过空的实际,依据ZF302工作面过旧巷开采实践,对煤柱综采放顶煤回收工作面过旧巷前后的顶板状况及矿压显现进行了描述,着重论述了煤柱综放回收工作面过旧巷回采过程中所采用施工工艺和对顶板、设备、通风、旧物回收等方面的技术管理,并总结出了许多宝贵经验。

Aiming at the reality of frequently passing empty areas in coal pillar fully mechanized top coal recovery working face in coal extraction process, according to mining practice through old roadway in ZF302 working face, described the roof condition and mining pressure appearance before and after passing though the old roadway in coal pillar fully mechanized top coal recovery working face, focused on the construction technology applied and technical management of roof, equipments, ventilation, old mate- rial recycling, etc., and summed up a lot of valuable experience.
