摘要
文章从工作面设备选型配套、巷道布置与块段划分、巷道掘进与支护、工作面回采工艺、顶板管理与控制、工作面通风方式等几个方面论述了行走支架护顶房柱式短壁开采技术在乌兰木伦矿61204工作面的现场应用情况,结果表明,行走支架护顶房柱式短壁开采技术实现了顶板的安全有效控制和工作面全负压通风,大大提高了工作面回采率,有效解决了我国现行短壁开采过程中存在的煤柱留设多、通风效果差、顶板垮落较难控制等问题。
From a equipment selection and matching of a coal mining face, gateway layout and block section divided,gateway driving and support, mining technology of the coal mining face, roof management and control, ventilation methodof the coal mining face and other aspects, the paper introduced the site application conditions of the walking poweredsupport for roof control and the room and pillar shortwall mining technology to No. 61204 coal mining face in Wulan MuluenMine. The results showed that the walking powered support for roof support and the room and pillar shortwall miningtechnology realized the safety and effective control of the roof and full negative pressure ventilation of the coal mining face,highly improved the mining rate of the coal mining face and effectively solve the many coal pillar left, poor ventilationeffect, roof falling and difficult control problems existed in the present shortwall mining process in China.
