The Study Of Water-filled Treatment For Yuanbaoshan Opencast Dump

As the needs of product for Yuanbaoshan opencast,the dump would be build.The water-filled is the key factor for the dump stability,and therefore the water-filled treatment need to design for the slope.By analyzing the hydrogeological conditions,engineering geological conditions of Yuanbaoshan opencast,the water filled and supplied are analyzed,and the dump slope sections are determined to develop appropriate measures.The rainfall runoff and groundwater inflow are predicted respectively.And fuzzy neural network is established to predict the dump water inflow,which found by inputs with the history day inflow in the section,internal dump groundwater inflow forecast,Based on the forecast results the control measures include partitioning and centralize are designed for each section dump.Firstly,the dewatering wells are designed for the east slope;three different forms tubular sewer are proposed for the different engineering geological conditions,which are downslope tubular sewer,polyline tubular sewer,the external sump tubular sewer.The results of this paper have certain reference value to mine production safety and to other similar coal mine construction.
