淮河以北矿区地面沉降及其成因

STATUS AND REASONS OF SURFACE SUBSIDENCE IN THE MINING AREA ON THE NORTH OF HUAI RIVER

摘要: 根据多年的高程实测资料,查明了淮河以北矿区(主要是潘集地区)地面沉降的幅度、速率及范围;分析了该区地面沉降的内因和外因,为区内地面沉降的防治提供了依据。

Abstract: The range, speed and area of surface subsidence in the mining area on the north of Huai River are known by leveling the surface elevation many times for many years. On this basis, various factors which caused the surface subsidence are analysed and this is valuable for the surface subsidence control.
