Abstract

See full text

The present disclosure relates to the technical field of mine ventilation, and in particular, to a three-dimensional ventilation method and system for mining by 110 construction method in coal and gas outburst mines. The three-dimensional ventilation method comprises: constructing a first process roadway and/or a second process roadway before stopping the working face; forming a first roof-cutting and roadway retaining section by a part of the working face track gate located in the goaf, and/or forming a second roof-cutting and roadway retaining section by a part of the working face transport gate located in the goaf during the stopping process of the working face, so that the air inlet of the first roof-cutting and roadway retaining section enters the gas drainage air return roadway through the first process roadway to form return air, and/or the inlet air of the second roof-cutting and roadway retaining section enters the gas drainage air inlet roadway through the second process roadway to form return air, the three-dimensional ventilation system is constructed by using the gas drainage air inlet roadway and the gas drainage air return roadway, during the conversion from the 121 construction method to the 110 construction method, a complete ventilation system can be formed in the roadway retaining section, real-time monitoring of the roadway retaining section can be carried while eliminating harmful gas accumulation in the retaining section.
