阳西矿区从+42米水平开采后,采区地表岩土随之移动下沉。经竖井+8米、-25米水平的开采,地表岩层移动更为剧烈,形成数条断裂带,有的落差竟达3米多;南北走向的裂缝大小有数十条。阳山顶标高+338米处西侧20米处也出现裂缝。现-58米水平开采过半,尤其5810-1采区的开采,使地表岩移向纵深发展。15、16勘探线之间地形陡峭,倾角45°以上,虽然矿体倾向与山坡倾向相反,但随着开采水平的降低,岩层移动引起大滑坡的可能不容忽视。有人预言,如阳山滑坡将危及竖井工业广场,井架、卷
Yangxi mining area from the level of +42 m after mining, mining area along with the soil surface subsidence. After excavation of +8 meters and -25 meters in the shaft, ground rock layers move more violently, forming several fault zones with some drops of up to 3 meters. There are dozens of cracks in the north-south direction. Yangshan Ding elevation +338 meters at the west of 20 meters also cracks. Now -58 meters horizontal mining more than half, especially mining 5810-1 mining area, the surface rock to move to the depth of development. 15,16 The steep terrain between the exploration lines is more than 45 °. Though the tendency of ore bodies tends to be opposite to that of the slopes, as the mining level decreases, the large landslides caused by the movement of rock strata may not be neglected. Some people predict that such as Yangshan landslide will endanger the shaft Industrial Square, derrick, roll
