a way through the empty alley

Abstract

The invention discloses a method for passing through an abandoned roadway. The method for passing through the abandoned roadway comprises a method for allowing a coal face to pass through the abandoned roadway. The method for allowing the coal face to pass through the abandoned roadway comprises the following steps: S01: marking a first intersection area intersected with the coal face in the abandoned roadway in advance; S02: sequentially distributing at least two mutually-independent first support timber cribs along the advancing direction of the coal face in the first intersection area to support a first false roof; S03: allowing a coal cutter in the coal face to advance in a sectional way in the first intersection area to cut the first support timber cribs; and S04: allowing the coal cutter to sequentially advance according to the way in the step S03 until the coal cutter passes through the first intersection area. According to the method for passing through the abandoned roadway, the workload for dismounting the timber cribs is reduced by adopting the mutually-independent support timber cribs, the labor intensity of staff is alleviated, the workload is reduced, and the assuredprocessibility factor of the staff is improved.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a method for passing through a goblin. Background technique [0002] Thick coal seams are often mined in layers. A total of multiple cross-cuts (connection lanes) are arranged on the working face and the lower lanes, and the upper and lower sections are connected in layers. The wind tunnel passes through the rock formation and connects with the coal seam recovery roadway of the fully mechanized mining face, and completes tasks such as layering and connection of the working face, main transportation, auxiliary transportation and ditch formation ventilation system. [0003] The fully-mechanized mining face shall pass through the empty roadway in this layer during mining, and the roadway prepared for the lower layer of the working face shall be excavated along the floor of the roadway prepared for the upper layer. During the mining process of the fully mechanized mining face an...

When the mining face passes through the gob, the mine pressure in the gob is strong, and the wooden stack beams are crushed to death. The demolition work is very difficult, and the demolition time is long. The normal cycle progress of the mining face cannot be guaranteed, forming a vicious circle and restricting the safety of the mining face. advance

When excavating the lower layer Hengchuan roadway, part of the cross section of the upper layer Hengchuan roadway is exposed, and the upper layer roadway needs to be removed to support the full-section interlocking wooden piles, resulting in a large empty roof area, long exposure time, and a large workload for removing the wooden piles, which is not conducive to safety manage
