瓦斯抽采半径确定方法的研究与应用

摘要

Drainage radius, as one of major technical indicators in gas drainage design, is difficult to be determined. Therefore, the determining method was studied in details and the theoretical foundation, operating steps, and precautions were pinpointed. Taking a specific mine as the basis of research and practice, field test and numerical simulation are combined to determine the mining influential radius and effective drainage radius, which could provide a reliable foundation for the drainage design and field operation.%矿井瓦斯抽采设计过程中，抽采半径是其中的主要技术指标之一。针对抽采半径难以准确确定的难题，对抽采半径的确定方法进行了详细分析，明确了不同方法的理论依据、操作步骤与注意事项。以具体矿井为研究与应用基础，通过现场试验测定和数值模拟相结合的方法，准确确定出了矿井的抽采影响半径和有效抽采半径，为矿井的抽采设计和现场操作提供了可靠的依据。
