我国大陆地区煤矿2014年以来新增地下空间资源研究

我国煤矿地下空间资源丰富。本文对2014年-2018年上半年煤矿井新增的地下空间资源进行了估算,并对其空间分布进行了分析研究。估算表明,2014年-2018年上半年,我国大陆地区新形成可利用地下空间资源为33.85亿m_³,其中关闭煤矿井井巷可利用地下空间资源为1.31亿m_³,因采煤形成的工作面可利用地下空间资源为32.54亿m_³；因煤矿山关闭和采煤新形成的可利用地下空间资源较多的省份有山西省、内蒙古自治区、陕西省、贵州省、新疆维吾尔自治区等,新形成可利用地下空间资源主要分布于东北地区、华北地区、西北地区。

Research on Newly Formed Underground Space Resources of Coal Mines in Mainland China Since 2014

ion: In China, the underground space resources of coal mines are abundant. This paper estimates the newly formed underground space resources from 2014 to the first half of 2018, and analyzes and studies their spatial distribution. It is estimated that from 2014 to the first half of 2018, the newly formed available underground space resources are 3.385 billion m3 in mainland China, among which the availiable underground space resources of closed mines are 131 million m3, and the available underground space resources of working face formed by coal mining are 3.254 billion m3. The provinces with more underground space resources due to the closure of coal mines and coal mining are Shanxi Province, Inner Mongolia Autonomous Region, Shaanxi Province, Guizhou Province, Xinjiang Uygur Autonomous Region, etc. The provinces with more underground space resources of closed coal mines and coal mining have Shanxi Province, Inner Mongolia Autonomous Region, Shaanxi Province, Guizhou Province, Xinjiang Uygur Autonomous Region, etc. The available underground space resources of newly forming by coal mining are mainly distributed in Northeast China, North China, Northwest China.
