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。
Sealed mines in the mine closed leak-proof water drains with a leak-proof wall drain device, the installation of the use of coal mines closed wall, regardless of water or water can be closed. The utility model can not only ensure that the gob area is sealed and air-tight when the water is in the absence of water, and can prevent coal spontaneous combustion accidents caused by the air leakage; but also ensures timely and smooth outflow of water when there is water in the gob area, preventing the water level increase, High-pressure water rushing to open the confined wall lead to water inrush accident; the same time also set to prevent the drain pipe is blocked from the slag opening, open the slag outlet can drain the cinder and other debris discharged so that the stagnant water can be smooth.
