摘　　要：为确定顺层钻孔抽采有效影响半径,以临涣煤矿10116工作面岩浆岩对10煤层的不同侵蚀区为研究对象,开展岩浆岩侵蚀及其影响区域顺层钻孔抽采有效影响半径的研究。结果表明:岩浆岩不同侵蚀区域的瓦斯抽采有效影响半径随抽采时间的延长而相应增大;当抽采时间相同时,侵蚀影响区与部分侵蚀区的有效影响半径相同;瓦斯抽采有效影响半径最大的是岩浆岩部分侵蚀区和侵蚀影响区,其次是非侵蚀区,再次是严重侵蚀区。研究结果有助于提高瓦斯抽采效率,为岩浆岩侵蚀条件下的矿井煤层安全高效开采提供安全技术支撑与保障。In order to determine the effective influence radius of bedding drilling,this paper takes different erosion zones of 10 coal seams on the magmatic rock bed of coal mine 10116 working face as the research object,and carries out the research on the effective influence radius of stratified drilling and extraction in magmatic rock erosion and its affected areas The results show that the effective influence radius of gas drainage in different erosion areas of magmatic rock increases correspondingly with the extension of extraction time;when the extraction time is the same,the effective influence radius of the erosion-affected area is the same as that of the partial erosion area;when the extraction time is the same,the largest effective radius of gas drainage is the partially eroded area and the affected area of magmatic rock,followed by the non-eroded area,and then the severely eroded area.The research results help to improve the efficiency of gas drainage,and provide technical support and guarantee for safe and efficient mining of coal seams in mines under the condition of magmatic rock erosion.
