摘　　要：金沙县龙潭组底部15^(#)煤层平均厚度1.81 m,为全区可采的稳定煤层,但因受其下伏茅口组灰岩水的影响迟迟没有开采。通过研究金沙县茅口组灰岩水富水特征,采用突水系数法,结合15^(#)煤层与茅口组灰岩之间的隔水层情况,分矿区研究了茅口组灰岩水对其上覆15^(#)煤层的影响程度。通过开采实践,例证了研究成果的准确性。The average thickness of No.15 coal seam at the bottom of Longtan formation in Jinsha county is 1.81 m,which is a stable coal seam that can be mined in the whole area.However,due to the influence of the limestone water of Maokou formation under it,it has not been mined for a long time.By studying the water rich characteristics of Maokou formation limestone in Jinsha county,using the water inrush coefficient method and combining the water resisting layer between No.15 coal seam and Maokou formation limestone,the influence of Maokou formation limestone water on its overlying No.15 coal seam is studied by mining area.The accuracy of the research results has been demonstrated through mining practices.
