海孜矿井为年产煤1.5Mt的大型矿井,主井装载硐室施工是与主井永久锁口和主井井塔施工同时进行的。此时副井的永久系统已形成并已交付使用,井底车场和主要运输大巷已施工完,主井与上一采区、中一采区和中二采区贯通并转入采区工程开拓。主井箕斗装载硐室的施工方案就是在上述具体条件下选择的。 一、工程概况 海孜主井箕斗装载硐室位于主井西侧,在马头门底板水平以下约24m处,硐室的上室与三个圆筒式煤仓下部皮带机巷机头硐室相连,整个硐室均与主井井筒紧密相邻(图1)。
Haizi Mine is an annual output of 1.5Mt coal mine large, main shaft loading chamber construction is the main shaft permanent lock and the main shaft of the tower at the same time. At this time, the permanent shaft system of auxiliary shaft has been formed and delivered. The underground parking lot and main transportation lanes have been constructed. The main shaft and the previous mining area, the first mining area and the second mining area are connected and transferred to the mining area open up. The main shaft skip loading chamber construction program is selected under the above specific conditions. First, the project overview Haizi main shaft skip loading cave is located west of the main shaft in Ma Tau door floor level below about 24m, the upper chamber of the chamber and the three lower cylinder belt conveyor Lane head machine The chamber is in close proximity to the main shaft (Figure 1).
