岩溶地区矿山开拓巷道而引起地下水的突然溃入造成矿井淹没,设施受损,甚至人员伤亡,已为众所周知,由于溃水而引起一系列诸如地面下沉开裂,塌陷,工业及民用建筑遭受破坏,在矿山中产生的损失已越来越大,笔者想借此短文阐述个人的粗略浅见,提供讨论。 1965年12月某日,广东某岩溶矿在离地面以下100多米深处掘进巷道时迂大量的地下水突然溃入巷道,矿井二个中段全部淹没,此后在矿山恢复及长期疏干排水的过程中,以涌水地段为中心,以2公里为半径的范围内出现一千六百多个大小不等的塌陷,致使农田、公路、铁路、桥梁、河流及大批建筑受到程
It is well-known that due to the collapse of water, a series of problems such as ground subsidence cracking, collapse, damage to industrial and civil buildings caused by the sudden collapse of underground water caused by the sudden collapse of groundwater caused by mine excavation in the karst areas, The loss in the mine has been growing, I would like to take this essay to describe the personal rough, to provide discussion. One day in December 1965, when a certain karst mine in Guangdong drove a tunnel more than 100 meters below the ground, a large amount of underground water burst into the roadway and all the two middle sections of the mine were submerged. Since then, during the period of mine recovery and long-term drainage and drainage , With more than 1,600 collapses of different sizes within a radius of 2 km centered on the gushing water area. As a result, farmlands, roads, railways, bridges, rivers and a large number of buildings are affected
