夹河矿工业广场煤柱条带开采技术研究

Study of Coal Pillar Strip Mining under Industrial Square of Jiahe Coal Mine

夹河煤矿经过几十年的开采,已进入矿井开采后期阶段,煤炭资源逐渐减少,生产接续日趋紧张,为了最大限度地采出煤炭资源,同时保证工业广场建(构)筑物正常使用,夹河矿进行了工业广场煤柱条带开采的研究与实践工作,先后开采了8个条带工作面,采后地表各类建筑物完好无损,没有出现损坏,开采取得了良好的经济效益和社会效益,实践成功经验和获得的开采沉陷相关参数,为今后类似开采提供了科学借鉴。

After many years mining in Jiahe coal mine, then mining arrived the last stage, and coal resources decreased slowly, and production continuing was tension day by day, in order to mining coal resource farthest and construction on industrial square could be using normally at the same time, industrial square strip mining was applied in Jiahe coal mine, and eight strip mining face was mining one after another, all kinds of constructions were intact after mining, favorable economic benefit and social benefit were obtained, it could be referenced for similar situation.
