Embodiment Construction
[0011] A treatment method for passing through a collapse column in a fully mechanized mining face, specifically, after the coal mining face is arranged, the details of the collapse column 6 are carefully detected in the two lanes of the air inlet lane 1 of the working face and the return air lane 2 of the working face position, according to the length range of the subsidence column 6, construct two or more gangue outlet measure lanes 4, and then design and arrange one or more longitudinally arranged gangue outlet contact Hengchuan 5 according to the width range of the subsidence column 6, and the gangue outlet measures lane 4 passes through the outlet Gangue contact Hengchuan 5 is connected with each other and connects with the return air lane 2 of the working face to form a ventilation system. Through the construction of gangue outlet measure lane 4 and gangue outlet contact Hengchuan 5, most of the gangue in the collapsed column can be pulled out and the gangue outlet can be e...

The invention relates to a new technology for mining coal in a coal mine, in particular to a processing method of passing sunk pillars on a full-mechanized mining working face, solving the problem that sunk pillars are difficult to effectively manage in the coal mining process existing in the prior art. The invention is characterized in that when the working face is arranged, the definite positions of the sunk pillars are accurately explored at two lanes, two or more gangue-exhaustion measure lanes are constructed according to the length ranges of the sunk pillars, one or more gangue-exhaustion communication horizontal plains are lognitudinally arranged according to the width ranges of the sunk pillars, the gangue-exhaustion measure lanes are communicated with each other through the gangue-exhaustion communication horizontal plains and are communicated with the air return lanes of the working face to form a ventilation system, a majority of gangues of the sunk pillars are pulled out through constructing the gangue-exhaustion measure lanes and the gangue-exhaustion communication horizontal plains, and the gangue-exhaustion measure lanes and the gangue-exhaustion communication horizontal plains are effectively supported so that the working face can directly cut the processed sunk pillars after mining to the gangue-exhaustion measure lanes and the gangue-exhaustion communication horizontal plains.
Description
technical field [0001] The invention relates to a new coal mining technology in a coal mine, in particular to a treatment method for a fully mechanized mining face passing through a collapsed column. Background technique [0002] The deposit conditions of underground coal seams in coal mines are complex, and the geological structures are complex and changeable. During the mining process, geological structures such as faults and collapse columns are often encountered. The so-called collapse column is due to the movement of the strata, and irregular rock bodies are embedded in the coal seam due to the collapse. At present, when collapsing columns are encountered in the fully mechanized mining face of coal mines, the methods of horizontal push hardening or whole or partial (tail) equipment relocation are usually adopted. It brings hidden dangers to safe production and restricts production progress. This method is only suitable for areas with relatively small collapse columns. ...
