摘要
根据充填开采的特点,针对某煤矿的煤层地质条件,对不同配比的充填体进行了实验室试验,结合现场最终确定了科学的充填材料配比和"见七充四"的泵送矸石充填方式。现场工业性试验表明该技术是成功且高效的,该成果已取得了明显的社会经济效益,对类似矿井有一定的借鉴作用。
According to the characteristics of mining with filling and the geological conditions of coal seams in a colliery,the authors make laboratory tests on different proportion of filling bodies,which helps to determine the scientific proportion of filling material and filling method with feeding gangue by pump.The on-site industrial test indicates the technology is successful and effective,which has achieved noticeable social economic effects and provided a reference for similar collieries.
