The invention aims at providing a drainage roadway for preventing and controlling coal and gas outburst in coal roadway driving, so as to solve the above problems. The drainage roadway for coal and gas outburst prevention and control is used for coal roadway driving. The drainage roadway is located in the upper strata above the coal seam. An air intake channel and a return air channel are located in the coal seam.
The drainage channels are located in the lower strata below the coal seam.
The first drainage channel group is sequentially arranged near the low-level drainage roadway. The top ends of the drainage channels are all connected to the low-level drainage roadway. The invention has the following advantages and technical effects over prior art:
– The drainage roadway is located above the coal seam, reducing collapse.
– Compared to the gas control roadway in prior art, it has a short construction time, low construction cost, and less underground work.
– It reduces workers’ effort, ensures their occupational health, and increases safety and social benefits.
– The invention improves the gas drainage of outburst mines and reduces their production costs.
– It improves economic benefits, social benefits, and production efficiency.
