在化工部化学矿山局组织的化工矿山“攀高峰”竞赛活动中,我们大搞双革,形成平巷掘进的装运卸机械化作业线,自五月十日至六月九日(其中停产一天),以三十个工作日,创开拓平巷(无支护)独头掘进月成巷443.63米的化工矿山新纪录。掘进工直接工效为0.369米/工班,创我矿历史最好水平,达到“攀高峰”竞赛规定的一级队标准。 施工条件 这次开拓平巷独头掘进,在马槽滩分矿六中段进行,用单工作面顺序掘进了6西2、6—2、6—1三条采区开拓运输巷。巷道均无支护、无水沟、断面为7.83米~2。巷道施工的地质简况如下;
In the Chemical Mine Climbing Summit organized by Chemical Mines Bureau of the Ministry of Chemical Industry, we engaged in double-leather production to form a loading and unloading mechanized operation line for roadheading. From May 10 to June 9, of which one day was discontinued, To create a new record of 443.63 meters of chemical and mining mines on the Moonrise Lane for 30 days. Excavator direct ergonomics 0.369 m / working class, a record mine the best level of history, reached the “climbing peak” race level one team standards. Construction conditions The pioneering roadway alone headway, in the marsh beach sub-ore six sections, with a single face sequence of tunneling six West 2,6-2,6-1 mining three open transport lane. Roadway without support, no ditch, section 7.83 m ~ 2. Geological conditions of roadway construction are as follows;
