摘要: The invention belongs to the field of coal-bed gas development geology and engineering non-conventional geological engineering, provides an industrialized method for coal district wells so as enable singular dispersive drilling, fracturing, discharging mining gathering transportation operation modes be developed modular layout-centralized wells. includes steps that well pattern design is carried out on a to-be-mined district, drill sites are arranged along panel main roadways, L-shaped adopted, drilling working face pillars conducted horizontal wells; in modularized mode, left right sides stope each site, multiple beds, drilled face, layout purpose achieved; plurality constructed at same time centralized mode by adopting technical processes including discharge integrated. Accordingly, achieved.
