中国关闭/废弃矿井的分类利用与等级评价

 针对关闭/废弃矿井分类利用和等级评价，使用Adaboost迭代算法，建立了一个关闭/废弃矿井利用的可能性等级模型，总结得出关闭/废弃矿井分类利用可分为：关闭/废弃矿井生态文明开发，关闭/废弃矿井地下空间开发利用，关闭/废弃矿井遗留媒体资源开发利用，关闭/废弃矿井地下水资源开发利用，关闭/废弃矿井气油水光互补能源开发利用。确立了20项分类指标进行关闭/废弃矿井等级评价，初步构建出国内关闭/废弃矿井资源数据库，提出关闭/废弃矿井智能精准开发科学构想，构建了关闭/废弃矿井绿色资源评价技术体系，推动关闭/废弃矿井精准智能开采以及城市转型发展。

Classified utilization and grade evaluation of closed/abandoned mines in China

With the transformation of the national energy strategy, a large number of closed/abandoned mines generate under the background of overcapacity reduction, mines closure/abandoning and the demand of high-quality development in the coal industry. In view of the fact that there is currently no complete system of classification utilization and grade evaluation for closed/abandoned mines in China, and the domestic energy structure is still dominated by coal in the short term, aiming at the classified utilization and grade evaluation of closed/abandoned mines, using the Adaboost iterative algorithm, a probability level model for the utilization of closed/abandoned mines was established. It was found that the classified utilization of closed/abandoned mines can be divided as follows:closed/abandoned mines ecological civilization development, underground space development and utilization, remaining media resources development and utilization, groundwater resources development and utilization, complementary energy (gas, oil, water and light) development and utilization. 20 classification parameters are selected as grade evaluation indicators for closed/abandoned mines, and a preliminary database of closed/abandoned mine resources in China is constructed. The closed/abandoned mine green resources evaluation technology system is established, and the scientific concept of intelligent and precise development of closed/abandoned mines is proposed. The research can promote the accurate and intelligent mining of closed/abandoned mines and the urban transformation and development.
