摘　　要：为了准确测定煤层瓦斯抽采半径,分析了影响瓦斯抽采半径测定的主要因素,并对主要影响因素进行了优化。通过在小屯煤矿采用相对瓦斯压力降低法现场测定表明,该方法用于测定瓦斯抽采半径效果较好,并结合抽采前后煤层瓦斯含量进行对比验证。In order to accurately determine coal seam gas drainage radius, analyses the main influence factors to determination of radius of gas drainage, and the main influence factors were optimized. The results shows that the relative gas pressure decreasing method is good by using in the xiaotun coal mine to determination of gas drainage radius, and combined with the coal seam gas content in gas-drainage beforeafter were compared verification.
