摘　　要：为准确考察地面钻孔抽采煤层卸压瓦斯的影响范围,为合理布置地面钻孔提供可靠依据。通过相似模拟实验研究了沿工作面倾向方向在13-1#煤层中应力分布情况,基于示踪技术综合考察和得出了地面钻孔抽采卸压瓦斯影响范围。结果表明:在保护层开采条件下北中央3采区地面钻孔抽采范围在倾斜方向在160 m以上,在走向方向上在240 m以上。In order to accurately study the influence area of coal seam gas pressure relief of surface borehole drainage,and provide a reliable basis for the reasonable arrangement of surface borehole,it studied the stress distribution along the working face in 13- 1#seam dip direction through the simulation experiment. Based on the comprehensive survey of tracer technique,it obtained the gas drainage influence area of surface borehole pressure relief. The results showed that under the protective layer mining conditions,the surface borehole drainage area of north central 3 mining area was 160 m above in the tilt direction,which was 240 m above in toward direction.
