Concurrent mining and reclamation for underground coal mining subsidence impacts in China
Large scale underground mining of coal resources in China using longwall mining has resulted in ecological and environment problems, including surface subsidence that is considered serious due to competing interests of prime agricultural lands, food security, and regional economic development.The subsided lands must be rehabilitated soon after mining to be agriculturally productive to minimize loss of farmland.Similarly, precious water resources must also be managed during and after mining to protect this natural resource.Toward these goals, the concept of Concurrent mining and subsidence reclamation (CMR) was proposed by Professor Hu of the China University of Mining and Technology,Beijing (CUMTB).Over the last two decades CMR concepts have evolved and successfully applied in the field in different parts of China.This innovative technology has increased available farmland during the mining process, and provided better land protection and food security in mining areas even with high groundwater table.The technology has been used in 5 of the 14 large coal bases in China.This paper describes the technology concepts, design and guiding principles for planning with two case studies from different regions to enhance its application both in China and in other countries.
