Abstract
本发明公开了一种煤的原位瓦斯放散初速度测定装置及方法，该装置中原位环境模拟模块包括：放置测试煤样的原位环境室，其外壳上加载有应力加载机；原位瓦斯气体制备模块包括：若干组分别储存有不同气体的储气组，各储气组均连有同一个气体混合室，气体混合室与原位环境室连接且两者之间设有增压装置和温控装置；瓦斯放散模块包括瓦斯放散空间、用于监测放散流量的流量传感器五，瓦斯放散空间与原位环境室连接。本发明能够真实模拟反映煤矿井下煤样等各类状态，测定结果更准确更具有参考性。与现有方法相比，能够更加精细准确的划分煤层煤与瓦斯突出危险区，增加煤与瓦斯突出预警的精确性和及时性，从而更加精细指导煤矿安全生产。
