临界距离老空水下薄煤层联合开采安全性分析

Analysis of the Safety of the Combined Mining of Thin Seams Under the Close Gob Water

以现场实测结果为基础 ,利用数值模拟与反演方法分析了薄煤层联合开采的顶、底板破坏范围。根据分析的结果评价了临界距离老空水下薄煤层联合开采的安全性。

Based on the site actual measurements, the inversion analysis on the destroy range of roof and floor by the combined mining of thin seams was made by using numerical modeling. Hereby the safety of the combined mining of thin seams under the close gob water was evaluated.
