王庄煤矿高产高效综放工作面端头支护技术

Abut Supporting Technology for High Output and High Efficiency Comprehensive Face Zone of Wangzhuang Coal Mine

根据王庄煤矿高产高效综放工作面设备配套、瓦斯治理、矿压显现、工作面回采顺序及巷道布置等情况,对工作面的端头支护进行设计,采用单体液压支柱加金属π型顶梁的联合支护方式管理端头顶板,取消了端头架,满足了安全生产需要,进一步提高了工作面的高产高效水平。

According to the situation of high output high efficiency face zone of fully mechanized for subleved caving associated equipment, fire damp prevention and cure, ground behaviour, face zone ranking and roadway layout, this paper designs abut support of face zone, manages abut roof in united support method of combining monomer hydraulic prop and type-πmetal cap, cancels the abut holder, meets the needs of safety production, and improves the level of high output high efficiency in face zone in further step.
