摘　　要：在膏体充填开采中,由于膏体的特殊形态,采取传统的流量计测量技术是不可行的,研究探讨通过超声波测压技术与两点差压法解决该问题。采取超声波管外测压,改进并运用两点差压法,求得压力值,进而实时计算出膏体瞬态流量。实践表明,该方法简单实用,达到了测量的目的。The traditional flowmeter measurement is unfeasible in paste filling mining due to the special form of paste.Ultrasonic pressure measurement and two point differences measurement were studied to solve the problem. It uses ultrasonic to get the pipe inside pressure from outside, and using two point differences measurement to get the pressure value and then calculating the paste flow. The practice showed that the technology is available to measure paste flow.
