摘要
通过对沙曲矿影响上组煤底板太灰突水脆弱性的主控因素、上组煤底板太灰突水脆弱性评价专题图的建立、太灰突水脆弱性评价模型的建立、煤层底板突水脆弱性评价分区及模型的识别与检验(利用脆弱性指数法)对现开采的3#+4#煤层底板太原组灰岩的突水性作出综合研究评价,为矿井防治水工作提供科学指导。
On the basis of main factors of Taiyuan formation limestone water inrush vulnerability of upper coal group floor in Shaqu Mine,the establishment of assessment thematic map and assessment model of water inrush vulnerability,and the assessment zones of water inrush vulnerability of floor and the identification and examination of model using vulnerability index,the comprehensive assessments were made on water inrush risk of Taiyuan formation limestone of No.3 and 4 floors,providing a scientific guidance for water inrush prevention and control in the coal mines.
