新型主动式测定钻孔瓦斯压力系统的研制及应用

针对目前煤矿测量瓦斯压力的测定值偏小、测定工作费时费力等问题,提出了一套能够快速连接的新型主动式测压系统。通过实验室测试与现场应用,该新型主动式测压系统的安装时间只需传统主动式测压系统安装时间的20%,测定值比被动式测压系统增加了9%~13.8%,与传统的主动式测压系统相比增加了2.7%~7.5%。该新型主动式测压系统具有连接快捷、安全耐用、密封性好、成本低的优点,具有很好的推广价值。

Development and Application of New Active Gas Pressure Determination System

According to the problems of coal mine gas pressure determination now,such as determination value relatively small,and determination working time and vigour,and so on,puts forward a set new active gas pressure determination system.By laboratory measurements and field application,the results show that the installation time of this system is 20% of traditional active pressure determination system,the determination value is added 9%~13.8% than passive gas pressure determination system,and added 2.7%~7.5% than the traditional active system.This new active gas pressure determination system has many advantages,such as connection rapidly,safety durable,better sealing,lower cost,and it is of great practical value.
