Suitability Evaluation of Repurposing Coal Mine into a Pumped-storage Power Station
摘要
Abstract
To evaluate the suitability of repurposing coal mine shafts for pumped-storage power stations,a index system for construction suitability evaluation is established,which encompasses 16 indicators across four major categories of geology,hydrology,mining conditions and power station design.The influences of evaluation indicators on construction suitability and operational safety are analyzed.Quantitative grading and weight assignment for each indicator are performed using the analytic hierarchy process-fuzzy comprehensive evaluation(AHP-FCE)method,and the suitability evaluation methodology for such repurposing projects is proposed.Taking the Daliuta Coal Mine in the Shendong Mining Area as a typical case study,the 3D geological model of the mining area is developed based on its fundamental geological and hydrological conditions,along with its mining utilization plan,the feasible repurposing model for this mine is analyzed,and a quantitative suitability evaluation tailored to its actual conditions is conducted.The results indicate that the Daliuta Coal Mine's suitability for repurposing is rated as"Conditionally suitable".The recommended construction mode is semi-underground.The upper reservoir is advised to be sited at Sanbulagou Gully,while the lower reservoir is proposed for the goaf area of Coal Seam 5-2.The respective reservoir capacities of upper and lower reservoirs are 81.8 million m3 and 145 million m3,respectively,with a maximum water head differential of 211.5 m.This configuration demonstrates significant underground space utilization value and substantial potential economic benefits.关键词
