综放面侧向支承压力分布规律模拟研究

Numerical simulation study on the distribution of abutment pressure in fully-mechanized caving face

随着厚煤层放顶煤开采技术的日益推广,放顶煤矿压规律的研究逐步深入,然而厚煤层开采的侧向支承压力的研究比较滞后,由于侧向支承压力的分布规律对煤柱的留设,以及煤炭资源的回收率等问题具有重要的意义。采用数值模拟方法通过对综放采场侧向支承压力的研究对区段煤柱的留设提供了依据。

With the technology of top coal caving developing, the study on abutment pressure is behind . The attribution of abutment pressure is important to the design of coal pillar. So,the numerical simulation study on the distribution of abutment pressure around a top coal caving face has a large practical meaning.
