自动放水器在瓦斯抽放系统中的应用与改造

依据现行矿井抽放系统排水的难点,对自动放水器的结构进行了改造,理论分析了放水器的流速与浮标尺寸的关系,提出了放水器放水时间的计算公式,针对局部积水严重区域,提出了放水器并联工作的方法。实践证明,改进放水器的结构和安装方法后,满足了矿井实际生产时管路自动放水的需要,提高了抽放效率。

APPLICATION AND TRANSFORMATION OF AUTOMATIC DRAINAGE DEVICE TO THE GAS DRAINAGE SYSTEM

Based on the difficulties of the existing mine drainage system,the device structure of automatic drainage was modified.The pa-per analysis theoretically the relationship between velocity and buoy measurements of drainage device and proposed drainage devices formula for calculating the drainage time.For a serious area of local water,put forward the working methods of parallel drainage device.Practice has proved that,after improving the structure of and installation method of drainage,meet the needs of pipeli...
