焦作矿务局九里山矿是一座设计年产量为90万吨的矿井。它的主井箕斗装载峒室,是在主井井筒、井底车场及主要运输巷全部形成以后才组织施工的,我们在考虑施工方法时,充分注意了这一特殊条件。 箕斗装载峒室的施工,是与地面永久建筑工程中的主井储煤仓、皮带走廊、空气加热室、井下圆筒煤仓以及其它工程的施工同时进行的。由于在施工中考虑了尽量利用永久设施的问题,因而缩短了施工工期,降低了工程成本,保证了矿井的按期投产。现将主要情况及认识作一概要介绍。 一、工程概况 九里山矿主井箕斗装载峒室为非通过式的,位于主井井口水平以下289.76米,高出
Jiuzhaigou Mining Bureau Jiulishan Mine is a designed annual production of 900,000 tons of mines. Its main shaft skip loading chamber was constructed only after the main shaft and well bottom and the main transport lane were all formed. We paid due attention to this special condition when considering the construction method. The construction of the skip loading chamber is carried out simultaneously with the construction of the main shaft coal bunker, the belt corridor, the air heating chamber, the downhole cylinder bunker and other works in the permanent construction of the ground. Due to the construction of the permanent facilities to take full advantage of the problem, thus shortening the construction period, reducing the cost of the project to ensure that the mine on schedule. Now the main situation and understanding of a brief introduction. First, the project profile Jiulishan Mine main shaft skip Loading room is non-through, located in the main wellhead level below 289.76 meters, higher than
