Abstract: The concurrent mining and reclamation(CMR) technology is based on dynamic subsidence prediction. Combined with the optimization of reclamation timing, dynamic elevation design and earthwork regulation, it realizes the spatio-temporal coupling of mining and land reclamation. Taking the Zhujidong Coal Mine as an example, the concurrent mining and reclamation scheme for the East No.3 Mining Area from 2024 to 2026 was studied, and the reclamation scope, water and soil layout, reclamation timing and construction scheme were determined. The results show that the concurrent mining and reclamation technology can significantly improve the land reclamation rate. The total reclamation area reaches 1.82 km², including 1.46 km² of cultivated land and 0.36 km² of water area. The land restoration rate is increased from 78.8% to 91.7%. The average reclamation cost of cultivated land is about 34.5828 million yuan per square kilometer. In addition, the total annual economic and ecological comprehensive benefit reaches 38.6075 million yuan. Compared with end-of-pipe treatment, the concurrent mining and reclamation scheme can achieve a balance of revenue and expenditure 1.3 years after reclamation, with remarkable economic and ecological benefits.
