摘要
阳泉矿区奥灰水位西高东低,西部15~#煤层已处于奥灰水位以下,承受一定的奥灰水压威胁。本文采用突水系数法进行带压开采分析评价,考虑峰峰组隔水层段的五类情况,将阳泉矿区带压开采分为安全区和基本安全区两个区块。针对阳泉矿区构造复杂的特点,提出安全带压开采的技术措施建议。
The Ordovician limestone water in Yangquan mining area is high in the west and low in the east. The No. 15 coal seam in the west is under the Ordovician limestone water level and bears a certain threat of Ordovician limestone water pressure. Considering the five conditions of the water-resisting layer of Fengfeng formation,the mining area above aquifer in Yangquan mining area was divided into two blocks of safety zone and basic safety zone with the water inrush coefficient method. In view of the complex structures of Yangquan mining area,technical measures and suggestions for mining above aquifer were put forward.
