The technical solution of the utility model is：A kind of mining closure plate, including it is fixed on Hatch Opening and for groined type structure Main body frame, the main body frame is fixedly arranged above cover plate, and the cover plate, which is provided with, to be used for installing the reserved of sliding cement pipe Sliding cement pipe hole, for installing the reserved air duct hole of air duct and for lifting by crane the reserved well-bucket hole of well-bucket and buffering, described pre- Stay and sliding door is provided with well-bucket hole, the sliding door includes the sliding rail of both sides and middle push-and-pull door-plate.

Preferably, the main body frame includes several vertical connections horizontal I-steel together and vertical I-steel, The web of the vertical I-steel is welded with the angle cleat positioned at junction, and the wing plate of the vertical I-steel is set in junction Jagged, the angle cleat is provided with least two screwed holes, and the web of the horizontal I-steel also is provided with positioned at junction Screwed hole, the angle cleat are connected by bolt with the web of the horizontal I-steel, and the height of the horizontal I-steel is big In the height of the vertical I-steel.

Preferably, the cover plate is the steel plate being welded on the main body frame.

Preferably, the sliding rail is the zigzag structure of two angle steel being centrosymmetric compositions.

Preferably, the push-and-pull door-plate is fixedly arranged above handle.

Preferably, the cover plate is fixedly arranged above cylinder, and the expansion link of the cylinder is connected with the sliding door.

The beneficial effects of the utility model are：

Mining closure plate of the present utility model, sliding door is set at reserved well-bucket hole, is easy to open and closes, it is anti-to stop dropping Also sliding door can be opened while falling when carrying out explosion, buffer shooting air-flow, prevents closure plate because explosion is damaged；Sealing Disk is easy to process and gathered materials on the spot using conventional steelworks such as I-steel, angle steel and steel plates；Push-and-pull door-plate can manually use handle Promote, convenient operation, can also be promoted with cylinder, avoid someone from arbitrarily opening sliding door.
