摘要
本文用相似材料模拟,现场实测等方法研究放顶煤开采覆岩活动规律。阐述了对采场矿压有明显影响的顶板构成及各自运动特点;提出了简单实用的顶板静压计算模型与方法。
Based on the similar material simulation and prectical experiment in situ, the movement charactedistic of overburden strata of longwall sublevel caving method has been studied in the paper. The roof beds structure and their movement features which have obvious effect on underground pressure manifestation are presented. A simple and useful method for calculating the static roof pressure has also been disscussed.
