The invention provides an upward-opening full-automatic disaster prevention device of a coal mine; the device mainly comprises a ground control device, a sensor control device, a grating door, a prevention door, a gutter hydraulic gate, a shutter device, an electro-hydraulic integrated cabinet and a door buffering device. The upward-opening full-automatic disaster prevention device of the coal mine is arranged in one way or symmetrically in two ways below the coal mine. According to the upward-opening full-automatic disaster prevention device of the coal mine, the grating door can be closed before the whole device is turned off safely, so that impurities in water are intercepted, and the influence of impact wave produced in various explosion and the carried impurities on the closing of the prevention door and destructive impact are mitigated. Particularly the device is required to intelligently, quickly and comprehensively block and prevent various disasters in one way or two ways when the prevention device is quickly turned off. The grating door and the prevention door are provided with rescue doors.
Description
technical field [0001] The invention relates to a mine disaster blocking and preventing device, in particular to a mine top-opening fully automatic disaster blocking and preventing device. Background technique [0002] At present, when disasters occur in mines involving fire, water, explosion, harmful gas, high-density coal dust, etc., it has not been found that the use of fully automatic energy to comprehensively block fire prevention, water, explosion, harmful gas, etc. High-density coal dust and devices to prevent, reduce or eliminate disasters and losses, especially when the blocking device is required to be closed very quickly, cannot effectively control the underground roadway, cavern, etc. itself and the water inrush, gushing water, Harmful gas exceeding the standard, high-density coal dust accumulation, gas and coal dust explosion and other disasters are realized intelligently, quickly, and comprehensively blocked and prevented. Serious accidents often occur and huge...
