新型钻孔瓦斯涌出初速度测定装备
The New Measurement Equipment of Drilling Gas Inrush Initial Velocity
摘要
Abstract
the drilling gas inrush initial velocity is one of common predictors for coal and gas outburst. With the increasing of drilling depth, however, the accuracy of prediction decreased, which led to the predict depth shallowed and severely restricted the increasing of excavating velocity. Through analyzing the stress state of measuring equipment when it measured the drilling inrush initial velocity, the stress conditions of the capsule in different positions were achieved, and the thought about new measuring equipment of drilling gas in- rush initial velocity was put forward, the corresponding equipment was created, and field test was conducted. The result showed that the measurement depth of new drilling gas inrush initial velocity measuring equipment was deeper than the traditional equipment.关键词
