The invention discloses a method for improving drilling gas extraction efficiency. According to the method for improving the drilling gas extraction efficiency, on the basis that a series of gas extraction holes are formed according to a traditional gas extraction method, a controllable pulse vibration device is arranged in a gas control roadway above a target coal bed, wherein the distance between the target coal bed and the gas control roadway ranges from 15 meters to 30 meters, and the controllable pulse vibration device is small in occupied space and intrinsically safe, and has controllable energy; pulse impact vibration is carried out on the controllable pulse vibration device, and acts on a roof arranged above the target coal bed to be mined. Due to the fact that pulse vibration is applied to the roof arranged above the target coal bed to be mined, corresponding pulse impact is borne by a coal body of the target coal bed, extension of an original crack in the coal body is facilitated ...

The invention provides a tilting cart which comprises a cart frame and a cart hopper arranged on the cart frame. The two ends of the cart hopper are hinged to the cart frame through rotating shafts. The cart frame is provided with an idler wheel group and at least one fixed pulley. The idler wheel group comprises a support fixed on the cart frame, a center shaft supported on the support and an idler wheel. The idler wheel is arranged on the center shaft in a penetrating mode and is in transmission connection with the center shaft. A rope is arranged on the idler wheel in a winding mode. One end of the rope is fixed on the idler wheel. The other end of the rope is wound through the fixed pulley and is hung at the position, far away from the rotating shafts, of the cart hopper. The idler wheel or the center shaft is driven to rotate in the forward direction through a power end, so that the rope is wound on the idler wheel, the rope is tightened, so that the cart hopper and the rope hanging ...
