煤矿采空区密闭墙防漏风放水器

Coal Mine Goaf Water Seal Air Leakage Prevention Device

煤矿采空区密闭墙防漏风放水器采用了密闭墙防漏风放水装置,安装使用在煤矿井下密闭墙体上,无论放水或无水状态,均能实现严密封闭。既能保证采空区无水时密闭不漏风、防止漏风造成煤炭自然发火事故;又能确保采空区有水时能够及时、顺利流出,防止由于密闭墙内水位升高、水压增大,高压积水冲开密闭墙酿成突水事故;同时还设置了防止放水管被堵塞的放渣口,打开放渣口可将放水管里煤渣等杂物排出,使积水能够顺利流出。

Coal mine goaf water seal air leakage prevention device adopts the water seal air leakage prevention device, installed in the coal mine closed on the wall, in any water or no water condition, can achieve tightly closed. Goaf water can be ensured when the airtight no air leakage, to prevent air leakage caused by coal spontaneous combustion accident; And to ensure smooth flow of goaf water in a timely manner, and prevent the airtight wails higher water, increase water pressure, high pressure water made airtight wall caused water inrush accident; Also set up to prevent discharge pipe blockage of slag, slag hit open mouth such as cinder in conduit can be put sundry, allow water to flow smoothly.
