大倾角煤层开采岩移基本规律的研究

Basic behaviour of strata movement in seam with deep dip angle

摘要: 针对南桐矿务局南桐煤矿大倾角煤层的复杂条件 ,运用实验室相似模型试验和基于显式有限差分基础上的FLAC程序 ,对南桐煤矿二井三区煤层开采引起的岩体移动、矿山压力分布和地表沉陷的基本规律进行了研究 ,所得结果对现场开采具有一定的指导作用

Abstract: According to the complex conditions of seam with deep dip angle in Nantong coal mine, model test and calculation with FLAC program are carried out to predict strata movement, ground pressure and subsidence due to mining. The obtained results are of referential value for engineering practice.
