The invention relates to a method for comprehensively treating the
ecological environment of a
coal gangue hill, which belongs to the field of mineral
waste treatment and
ecological environment restoration. The method mainly solves the problems of fire
extinction,
fire prevention and
vegetation construction of the
coal gangue hill. The method comprises the steps: the on-site reconnaissance of the
coal gangue hill is carried out, and a construction operation plan is established; with
fire prevention as principal and the combination of
fire prevention and fire
extinction, the fire prevention is crucial and is combined with the fire
extinction, a
thin layer of
slurry is firstly sprayed on the
coal gangue hill by a mechanical method to completely seal to form a sealing layer (8), transition
slurry is sprayed on the sealing layer (8) to completely cover the sealing layer (8) to form a
transition layer (9),
slurry containing grass-
shrub vegetation is spayed on the
transition layer (9) to completely cover the
transition layer (9) to form a planting layer (10); the
contour line girdle band type operation in the spraying process is carried out from bottom to top to gradually and completely cover the hill, and different operating
modes are selected according to practical conditions. The invention can not disturb the structure of the
coal gangue hill, takes the fire prevention as the principal, combines the fire prevention with the fire extinction, has good and durable fire prevention effect, uses reliable and effective fire prevention and fire extinction measures as guarantee conditions to construct the planting layer, adopts grass-
shrub plants, carries out hill sealing management and ensures
vegetation restoration; in addition, the method uses the prior specialized
mechanical devices to carry out construction operation, is easy to implement, has little difficulty, high efficiency and low investment and can ensure
treatment effect.
