[0047] 1. Terrace Section Optimization Considering Fracture Filling

[0048] Under normal natural conditions, the design section of horizontal terraces is as follows: figure 1 shown. In the figure, α is the slope of the original ground (°), β is the slope of the field ridge (°), H is the height of the field ridge (m), B is the width of the field (m), and the amount of earthwork V per unit length of horizontal terraced field construction (m 3 )for:

Abstract

The invention discloses a terrace type reclamation parameter optimization method considering mining subsidence deformation. The terrace type reclamation parameter optimization method comprises the following three parts: 1, a terrace section optimization method considering crack filling; 2, terrace section optimization considering surface gradient change; and 3, a terrace construction process considering crack filling: firstly, dividing a treatment area into a plurality of sections along the length direction of the terrace, dividing the sections into schematic diagrams, then treating by taking the sections as units, and determining the length of each section according to the operation benefit of construction machinery.

Description

technical field [0001] The invention relates to a treatment method for coal mining subsidence. Background technique [0002] The most commonly used method for the treatment of coal mining subsidence is terraced field reclamation. For continuous subsidence land, the control design can be carried out by referring to conventional water and soil conservation methods. However, in recent years, with the improvement of coal mining mechanization level and the increase of mining scale, subsidence cracks have become a typical failure form in coal mining subsidence areas. There is still a lack of detailed research on how to rationally design related treatment processes while considering surface deformation and fracture filling. If traditional methods are used for design and engineering quantity estimation, large errors may occur. The invention discusses the relevant technical parameters when adopting the terraced field treatment in combination with the topographical changes of the c...
