摘要
通过机械模拟与相似材料模拟相结合的方法,对放顶煤顶板结构下的支承压力分布规律进行了分析。结果表明,放顶煤采煤法其支承压力分布形式与分层开采法类似,但在量值及影响范围上有增减。该研究结果对分析放顶煤矿压显现特征提供了依据。
THE paper analyses the distribution pattern of abutment pressure under the condition of the main roof stnuture in sublevel caving mining with the way of mechanical and similar material simulation. The result indicated That the abutment pressure distribution form was similar to that of slicing mining method but its magnitude and affecting range changed. It provides a basis for analysing the mine pressure manifestation in sublevel caving mining.
