国家能源局日前在山东省泰安市召开全国煤矿充填开采现场会,将积极推广应用煤矿充填开采技术。国家能源局副局长吴吟指出,我国煤炭资源主要靠井工开采,传统开采方式容易引发土地塌陷、地下水流失、煤矸石占压土地等生态环境问题,带来采空区自燃发火、透水、瓦斯积聚超限等安全隐患;我国人均煤炭资源拥有量少,建筑物下、铁路下和水体下压煤量较大,影响矿井正常生产接续,
National Energy Administration recently held a national on-site coal mine filling and mining meeting in Tai’an, Shandong Province, and will actively promote the application of coal mining and filling technology. Wu Yin, deputy director of the National Energy Administration pointed out that China’s coal resources are mainly boring and mining, the traditional mining methods are likely to lead to land subsidence, groundwater loss, coal gangue and other ecological problems occupy the land, bringing gob of spontaneous combustion, water, gas Accumulation of overrun and other security risks; China’s per capita possession of less coal resources, under the buildings, under the railway and the water under the pressure of coal, the normal production of mine continuity,
