Study and application of building construction technology on surface ground above mine goaf

in order to scientifially utilize the mining subsidence areafor the bulding constrution on the surace ground and to ensure the salety and normal apliation of the new buildings with the theoretical studly and the stite practice combined method.the paper systematically studied the caculation of the ground residual defomation valu.the evaluation method of the found ation stability above the mine goaf the foundation realment technology and theanti- defomation technical measues ofthe new bulidings. During the bulcing constructed on the ground above the mine goathe min mining depth should be over the sumn of the faling & fractring zone heicht and the bulcing load infuence depth. During the buiding height was determined for the new builtings.the residual subsidence defomation value of the ground shoud be considered and especialy the ground inclined deformation value. When the shallow mining depth or the complicated geoloagcal mining cond ton could not met te requirements of the buiding to be constructed a groutng reatment to the mine goa should be considered. The technology was widely promoted and apaolie to Pngdngshan,T7angshan,Jincheng,Jiaozuo and other resource type cities and the obvious economic benefits and social benefits were obtained.
