针对我国中东部煤矿软岩、破碎顶板、斜巷大倾角复杂条件下运输重型液压支架的技术难题,中煤新集能源股份有限公司引进重型防爆柴油单轨吊机车设备,结合现场条件,对专用重型起吊梁单轨道安装方式、吊挂链条布置方式、单轨吊吊挂方式和吊挂机具、使用过程中现场管理等进行研究创新,首次实现用单轨吊整体运输48 t重型液压支架,运输效率较传统绞车运输提高50%以上,成功解决了综采工作面传统回撤工艺存在的准备量大、运输环节和人员多、运输效率与劳动效率低、安全管理复杂等问题,可实现复杂地质条件下综采工作面安全、高效、快速安装和回撤。

According to the technical problems of the heavy powered support under the conditions of the soft rock, broken roof, high inclined complicated gateway i n the coal mines of Mid-Eastern China, a heavy flameproof diesel engine monorail locomotive equipment was imported by China Coal Xinji Energy Company Limited. In combination with the site condition, a study and innovation was conducted on the installation method of the monorail for the heavy lifting beam, layout method of the su spended chain, the suspended method and suspended tool of the monorail, and site management during the application process. It was a first time for the monorail to tr ansport the 48 t heavy hydraulic powered support and the transportation efficiency was over 50% higher than the conventional winch transportation. Thus the monorail t ransportation could successfully solve the high preparation workload, many transportation links and personnel, low transportation efficiency and low labor efficiency exi sted in the conventional withdrawing technique of the fully mechanized coal mining face and could realize the safety, high efficient and rapid installation and withdrawin g of the fully mechanized coal mining face under the complicated geological conditions.
