摘要
三相泡沫发生器是三相泡沫瓦斯压力测定仪的关键部件。利用三相泡沫发生器解决了煤层瓦斯压力测定中封孔的技术难题。通过现场试验,取得了四钻孔平行测定试验压力值一致的结果,实现了煤矿井下煤层瓦斯压力的准确测定。
measuring Three-phase foam generator is the important part of three-phase foam gas pressure device, technological problem of measuring of gas pressure in stifled hole solved by use of this device, through on-spot testing, four hole gas pressure verified to be the same by operation, achieve exact measuring of gas pressure in underground coal seam.
