倾向条带矸石胶结充填开采技术研究及应用

摘要

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 mat%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。
