煤矿水仓有效容量监测方法研究

受煤泥淤积的影响,煤矿水仓有效容量缺乏可行的监测手段,因而难以达到规定的要求,存在一定的安全隐患。文章针对煤矿水仓中水质分层的现象,结合水仓结构特点,根据水位高度和煤泥淤积厚度计算出水仓有效容量和空仓量的表达式;设计了双浮球式液位传感器及浮球-超声波组合式液位传感器来直接或间接测量煤泥淤积厚度和水位高度,并提出了水仓状况动态监测方案,实现有效容量和空仓量的在线监测。

Study on Monitoring Method for Effective Volume of Water Sump in Coal Mine

Although effective volume and empty volume of water sump are important to drainage safety of coal mine, there are seldom study on monitoring them, thus trouble in safety is hidden . This paper, according to the layer phenomenon in water and the structure of water sump, calculated effective volume and empty volume of water sump based on water level and slime thickness, and designed two floats level sensor and float combined with ultrasonic wave level sensor that could detect slime thickness directly or indirectly and water level, which provided reference to apply dynamic monitoring on water sump in coal mine.
