Coal mining subsidence area administration method for loess hilly-gully region
The invention discloses a coal mining subsidence area administration method for a loess hilly-gully region. The method comprises the following steps: 1, measuring the width of a crack opening; 2, determining a crack administration scheme, wherein the crack administration scheme is an on-site filling method or a combined crack filling and micro-slope reconstruction administration method; 3, performing crack administration, wherein a crack to be administrated is filled with a soil body when the on-site filling method is adopted; the combined crack filling and micro-slope reconstruction administration method for administration comprises the following steps: 301, measuring an inclination angle of the crack; 302, judging an inclination angle value of the crack; 303, performing cross slope crack administration; 304, along-slope crack administration; 4, repeating step 1 to step 3 for many times until all subsided cracks in a loess slope of a coal mining subsidence area are administrated. The steps are simple, the method is reasonable in design, convenient to implement and construct and shorter in construction cycle, and has good administration effects, and the coal mining subsidence area of the loess hilly-gully region can be effectively administrated.
