| 摘 要： | 为了研究薄基岩浅埋煤层开采过程中覆岩活动规律,利用相似材料模型法,对大柳塔煤矿12305工作面进行了相似模拟实验,得出了薄基岩浅埋煤层开采过程中覆岩活动特点.结果表明,薄基岩浅埋煤层开采的覆岩活动规律与常规开采顶板活动规律存在根本区别,应该有其自身的开采理论指导现场生产.

| Abstract: | Devoted to studying the law of cover-rock movement in the course of mining in the shallow seam under thin base rock, the paper discusses the simulation of 12305 face by a model of resemble material in the Daliuta mine and offers cover-rock movement law governing the shallow seam under thin base rock. The results reveal a great difference between mining of shallow seam under thin base rock and conventional mining in the movement law. There arises necessity of developing a mining theory designed to the working site. |
