Abstract

The invention is suitable for the technical field of coal mine excavation and provides stamping ground pressure relief equipment which comprises a supporting device, a pressure relief device and a conveying device. The supporting device comprises a supporting frame, an opening and closing device and anchor rods, the supporting frame comprises an arc-shaped section and a straight edge section, theopening and closing device comprises a fixing base, a rotating plate and a plurality of blocking pieces, a containing space and a moving groove are formed in the fixing base, a limiting groove is annularly formed in the rotating plate, and a limiting column and a fixing column are arranged on the blocking pieces; the pressure relief device comprises a pressure relief drill hole and a blasting part, and the blasting part is located at the tail end of the pressure relief drill hole; the conveying device comprises a bearing plate, a guide rod, a moving rod and a rotating rod, the plurality of anchor rods are arranged on the bearing plate, the width of a guide groove is smaller than the diameter of the anchor rods, the moving rod is vertically connected with the guide rod in a sleeve mode, andan ejection column is arranged on a sliding block and located under the guide groove. Therefore, effective supporting and pressure relief of a rock burst roadway can be achieved through the stampingground pressure relief equipment, and the safety quality of follow-up work is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine excavation, in particular to a method and equipment for ramming ground pressure relief. Background technique [0002] Rockburst is a phenomenon in which the coal and rock masses around the shaft and stope release deformation energy under certain high stress conditions during the coal mining process, and the coal and rock masses are suddenly destroyed, collapsed or thrown out, accompanied by loud noises. And rock mass vibration, often cause support breakage, roof caving, roadway blockage, casualties. Rock bursts can also cause other mine disasters, including gas and coal dust explosions, fires, and interference with ventilation systems. In severe cases, they can also cause hazards similar to natural earthquakes, causing ground vibrations and building damage. Therefore, rock burst is one of the major disasters in coal mines. [0003] The mechanism of rock burst is very complicated. Scholars from...
