钻孔瓦斯涌出初速度是常用的煤与瓦斯突出预测指标之一，该技术最大的缺陷是预测深度较浅，严重制约着采掘速度的提高。针对传统装备的不足及现代化矿井高效开采的需求，提出了RS-1型柔性深钻孔瓦斯涌出初速度测定装备的结构与工作原理，对该装备的封孔胶囊进行了设计与加工制造，对该装备的性能进行了实验室实验和现场试验。研究结果显示，该装备具有测定钻孔瓦斯涌出初速度的功能，而且，能够有效提高测定钻孔深度。

Borehole methane discharge initial velocity is one of the usual prediction indices of coal and methane bursting , but for this method , shallow prediction depth seriously district mining and driving speed.In order solve the problem , RS-1 flexible deep-hole meas-urement equipment of methane discharge initial velocity was developed.Its structure and operating principle was introduced.Hole seal-ing capsule of this equipment was designed and manufactured.Laboratory and on-the-spot test showed that this equipment could measure methane discharge initial velocity and effectively improve borehole depth.
