Description
Technical field
The invention belongs to mapping and environmental monitoring technology field, particularly determine the technical method on the infringement border, arable land that subsides.
Background technology
Coal is the Chinese topmost energy, and along with developing rapidly of China's mining cause, it develops when the national economic development is played a significant role, and the problem of thereupon bringing also displays.A large amount of extraction of underground coal resource cause the balance of goaf superincumbent stratum to be destroyed, produce distortion, cause surface subsidence damage in various degree, the form of surface subsidence damage has: subsidence basin, collapse doline, step, surface cracks etc., in deifferent regions.China, its degree of subsiding is also different, such as in Eastern Plain district being the Chinese compound main producing region of coal-grain, the destruction enormous amount that underground exploitation is ploughed to ground, there is very serious surface collapse in many mining areas, and cause serious mining area ponding problem, the proportion that wherein infringement is ploughed is larger, Cultivated Land Area Decrease, quality degradation, badly influence the agricultural production of this area, the people's daily life.
According to existing mining subsidence and three unders in coal mining (refer under buildings, under railway and coal mining under water-bodies method) standard, subsidence basin refers to the region that submergence depth is greater than 10mm.And for ploughing, subsiding is greater than 10mm and agricultural production is not affected, Wei Fei disturbed area, this region, the region that crop yield is exerted an influence that only subsides is only the infringement region of ploughing.
The boundary demarcation that mining area destruction is ploughed at present lacks unified standard, cause in ground dispute is subsided in processing and cannot follow on the one hand, cause workers and peasants' aggravation of contradictions, also affected on the other hand the enforcement of land reclamation work, even coal industry is produced and also caused immeasurable loss.
Summary of the invention
The object of the invention is for solving an above-mentioned difficult problem, a kind of method of determining subsiding infringement border, arable land is proposed, be intended to make up subside and damage the deficiency that arable land boundary demarcation lacks unified standard, this method combines subside buffer model and DEM differential technique based on remote sensing ponding edge, can determine fast the border that subsides and plough, for compensation and the improvement on the ground that subsides provide shoring of foundation.
A kind of technical method of determining subsiding infringement border, arable land that the present invention proposes, is characterized in that, comprises the following steps:
1) choosing of data source and determining of the infringement regional extent of subsiding to be measured: the start time point occurring according to district to be measured infringement and carry out the time point of determining work in border and set section detection time obtains remotely-sensed data (comprise satellite, aerial remote sensing images and satellite, AEROSAT image cubic phase to) and the topographic map data (non-remotely-sensed data) of location, mining area phase when more than at least 2 different in this time period; Distribute and coal seam information and mining information (as mining engineering plan) according to the mining area coal obtaining, carry out prediction of mining subsidence, draw depression isogram, determine the preliminary scope in the infringement region that subsides to be measured;
2) subsided water area boundary information extracts: described remotely-sensed data is carried out to geometry correction, image co-registration, image enhancement processing, colored synthetic, image co-registration processing, and according to step 1) in determine preliminary range boundary, from remote sensing images, delete the image-region outside this preliminary range boundary; Utilize the method for multi-scale wavelet transformation rim detection to detect the border, waters in remote sensing images, and combination Typical Land survey information on the spot, determine and supplement extracting subsided water area boundary information; Described terrain data is carried out to geometry correction processing, and according to step 1) in the infringement preliminary scope in region of subsiding separation and Extraction in topographic map data of determining go out subsided water area boundary information;
3) the subside foundation of ground border buffer model and obtaining of surface collapse depth information: (mining area is all provided with subsiding observation station first to obtain the Ground Subsidence Monitoring data in district to be measured, regularly the observation station in research station is observed and obtained data with total powerstation), and according to settlement monitoring data, set up the exponential model of border, the ground buffering of subsiding by numerical simulation:
