新时期我国煤矿地下空间综合利用现状及展望

我国煤炭资源的长期大规模开采，产生了大量的地下空间，直接一关了之不仅造成地下空间资源浪费，还可能产生一系列安全、环境及经济问题，因此，如何科学、高效地解决煤矿地下空间的综合开发利用问题，对煤炭产业乃至国民经济的发展具有重要现实意义。笔者等以主要产煤省份为代表，结合调研收集的最新生产煤矿和关闭煤矿数据，深入分析了“十三五”期间生产煤矿地下空间和关闭煤矿地下空间总体情况，系统总结了国内外煤矿地下空间在储物、储能等方面的功能化利用现状，指出了当前我国煤矿地下空间利用存在资源数据信息匮乏、整体开发利用率低、相关技术研究工作仍相对滞后、可供推广借鉴的成熟示范工程较少等问题，提出了新时期煤矿地下空间基础数据库建设、利用体系构建、关键技术攻关、示范工程推广4个方面作为重点发展方向。

Present situation and prospect of comprehensive utilization of underground space in coal mines in China in the new period

Long- term large- scale exploitation of coal resources in China has produced a large number of underground spaces. Directly shutting it down will not only waste underground space resources, but also cause a series of safety, environmental and economic problems. Therefore, how to scientifically and efficiently solve the comprehensive development and utilization problem of underground space in coal mines is of great practical significance for the development of the coal industry and even the national economy. This article takes the main coal producing provinces as representatives and combines the latest data collected from research on production and closure of coal mines to deeply analyze the overall situation of underground space in production and closure of coal mines during the 13th Five Year Plan period. It systematically summarizes the current functional utilization status of underground space in coal mines at home and abroad in terms of storage and energy storage, and points out the scattered resource data information in the current utilization of underground space in coal mines in China, the overall development and utilization rate is low, related technology research work is still relatively lagging behind, and there are few mature demonstration projects available for promotion and reference. Four key development directions have been proposed in the new era, including the construction of coal mine underground space basic database, utilization system construction, key technology research, and demonstration project promotion.
