The invention relates to the technical field of mine water exploration protection, in particular to an emergency protection device for underground coal mine exploitation, which comprises a crawler, a water storage tank is fixed on the top surface of the crawler, a bent supporting plate is fixed at one end of the water storage tank, and a transmission pipe is rotatably connected to the top of the bent supporting plate. A connecting pipe is fixedly communicated with one end of the transmission pipe, a plurality of round holes are formed in the end, away from the transmission pipe, of the connecting pipe, an auger is fixed to the outer side of the connecting pipe, and a drill bit assembly is arranged at the end, close to the round holes, of the connecting pipe. According to the device, the crawler drives the connecting pipe, the auger and the drill bit assembly to rotate into the ore bed to form a water detection hole, gravel in a drill hole is conveniently conveyed out through rotation of the auger, an air pump conveniently blows outside air into the drill hole to dilute the gas concentration through a round hole in the connecting pipe, and the round hole can also convey liquid nitrogen to the position of the drill hole; therefore, the effect of temporarily and emergently plugging the drill hole is achieved.

    本发明涉及矿井探水防护技术领域,具体涉及一种煤矿井下开采用紧急防护装置,包括履带车,所述履带车的顶面固定有存水箱,所述存水箱的一端固定有弯折撑板,所述弯折撑板的顶部转动连接有传动管,所述传动管的一端连通固定有连接管,所述连接管背离传动管的一端开设有多个圆孔,所述连接管的外侧固定有绞龙,所述连接管靠近圆孔的一端设置有钻头组件。本发明中,通过履带车带着连接管、绞龙和钻头组件转动到矿层里面开设探水孔,绞龙转动方便将钻孔内部的碎石输送出来,连接管上的圆孔方便气泵将外界风吹送到钻孔内部稀释瓦斯浓度,圆孔也能够将液氮输送到钻孔位置,使积水被冻住,起到临时紧急封堵钻孔的作用。
