Remoulding method of landform of gangue accumulation area

Abstract

The invention discloses a remoulding method of the landform of a gangue accumulation area. The remoulding method comprises steps of using a drainage basin landform theory and a river landform geomorphologic shape mathematical model to simulate the natural landform; using an SEDCAD flood peak correction flow model to carry out complementation design on the remoulded landform; using the design model data to a civil engineering construction and designing module developed through the Carlson software; carrying out river channel protection engineering of the landform remoulding of the gangue accumulation area; and remoudling the landform and carrying out erosion potential evaluation. According to the invention, by introducing the drainage basin landform theory and the landform geomorphologic shape mathematical model into the landform design of the gangue accumulation area, errors caused by the mechanical method are reduced; meanwhile, the civil construction and design module is used for carrying out construction guidance; by use of the balancing of the reduction and the filling, workload and cost are reduced; the plant natural succession rule is obeyed, so the plant stability is improved; and quantitative reference is provided for the mining region recovery model.

Description

technical field [0001] The invention relates to a landform remodeling method in a coal gangue accumulation area, which belongs to the technical field of ecological restoration. Background technique [0002] Coal gangue occupies a large amount of land and causes spontaneous combustion, which is a well-known governance problem. At present, the vegetation restoration measures adopted in the coal gangue accumulation area are still conventional afforestation technical regulations, which are characterized by the design method of "staggered tire leveling and landscaping", occupying a large amount of land, the greening plants are not in harmony with the surrounding landscape, and the soil stability is poor , serious soil erosion. At present, the flood peak discharge model design with direct drainage is generally adopted: [0003] [0004] In the above formula, Q refers to the flow rate, Kp is the modulus ratio coefficient, m 3 is the volume and s is the time. [0005] In rece...

Problems solved by technology

[0006] It should be pointed out that the governance plan adopted in the above-mentioned coal gangue accumulation area focuses on empirical planning and landscape planning methods, which deviates from the technical concept and connotation of ecological restoration, thus forming landscaping technology or conventional afforestation technology, with obvious artificial signs and unstable slopes , high post-maintenance costs
