差异化支护形式施工技术在杨河煤业的应用

The Application of Differentiation Support Construction Technology on Yanghe Coal

巷道的掘进速度及质量对煤炭企业的生产接替有着重要的意义。为提高掘进速度、保证施工质量,公司提出了在42091综采工作面运输顺槽进行差异化支护的方案。通过"加大棚距+锚索"支护方式,达到了节约掘进成本、提高掘进速度及降低职工劳动强度预期效果。

The driving speed and quality of roadway of coal have a great significance for enterprise production. In order to improve the driving speed to ensure the quality of construction, the company put forward the scheme of using differentiation support in the transport crossheading of 42091 fully mechanized faces. Through ＂increasing shed distance ＋ anchor＂ support method, saving drilling cost, raising the drilling speed and reducing the labor intensity of workers are achieved.
