Abstract: The establishment of the evaluation index system and the selection of suitable evaluation methods are the main research contents of the land reclamation in the open pit. When selecting the evaluation index， some indexes such as the use of original land and the utilization status of the surrounding land were chosen. Besides， the selection method of the evaluation index in the soil was optimized. According to this， an evaluation model for the suitability of land reclamation in open pit based on FAHP-Entropy coupling weighting method was established， and the evaluation on the suitability of land reclamation in the east mining pit of the Tianshengba open pit was carried out. According to the evaluation results and the actual situation of the east mining pit in the Tianshengba open pit， it concludes that the platform and the slope of the east mining pit in the Tianshengba open pit should be shrubbery land. In addition， the bottom of the pit should be natural puddle. The evaluation index system and the suitability evaluation model established own good applicability， and can provide technical support for land reclamation in open pit.
