摘要:
水仓的有效容量及空仓量对于煤矿排水安全意义重大,长期以来一直缺乏对水仓有效容量监测的研究,存在一定的安全隐患。本文针对煤矿水仓中水质分层的现象,结合水仓结构特点,提出根据水位高度和煤泥淤积厚度来计算水仓有效容量和空仓量,并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,为矿井实现水仓状况动态监测提供了参考。
关键词: 水仓有效容量, 煤泥淤积, 动态监测
Abstract:
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.
