Technology for preventing and controlling spontaneous ignition of gas and coal dust by fully closing and withdrawing full-mechanized coal face

The invention discloses technology for preventing and controlling spontaneous ignition of gas and coal dust by fully closing and withdrawing a full-mechanized coal face. The technology includes: setting up a support system; arranging flame-retardant antistatic cloth; jacking the flame-retardant antistatic cloth to the top of a coal bed and fixing the same relatively to the coal bed with the help of the support system; enabling the flame-retardant antistatic cloth to fall down along with caving of coal at the top of a mined-out area and to be abutted against the rear portion and a baseplate of a support. The flame-retardant antistatic cloth is additionally arranged, and functions of closing the mined-out area, preventing gas in the mined-out area from gushing, stopping fresh air from entering the mined-out area, resisting flame and static electricity and preventing dust from flying can be realized in the process of withdrawing the fully-mechanized coal face, so that the defects of the prior art are overcome. A coal mining system comprises a base, a top beam and a tail beam. The top beam and the tail beam are arranged on the upper side of the base through an upright, and the flame-retardant antistatic cloth is arranged on the upper side of the top beam, can move relatively to the top beam and can be fixed relatively to the coal bed. The technology is used for withdrawing the full-mechanized coal face and is high in safety.
