A mosaic algorithm of different scale image registration and adaptive is proposed in this thesis, against to the large amount of calculation and poor robustness, as well as cannot well solve the problem of image mosaic of images who are in different scales in the traditional image mosaic method. The match and mosaic of different scale and rotated images is achieved through feature point matching and automatically recognizing of transform geometric parameters between images. First, using SIFT extraction algorithm to extract the feature points of the image to be mosaic. Second, achieving feature points matching according to the principal of mutual information maximum. Third, automatically recognize the relationship of transformation parameters between two images according to the geometric information of the matching pairs. Finally, the projective transformation matrix that reflected the image translation, rotation and scaling information can be obtained and the image stable mosaic can be achieved.

Abstract. After the impoundment of the reservoir, in the role of the water head, there will be seepage in the dam, which will produce the seepage of the dam, the dam cross section and intersection called saturation line. Saturation line is the lifeline of the safety of tailings dam, saturation line height is directly related to the dam stability and safety properties, when the saturation line depth is 0m, this will produce piping, which is the direct cause of the dam break Introduction. In water conservancy and hydropower, it is mainly to monitor the location and change of the line of the dam by calculating the height of the saturation line, determining the influence of the stability of the dam, in order to determine whether the dam is stable, to ensure the safe operation of the dam. Capacity, flow rate, precipitation can be intuitive monitoring of hydrological parameters Compared with above parameters monitoring saturation line is hidden, the monitoring and analysis is real-time and intuitive, automation and intelligent, so the system chooses mixed programming of MATLAB and VC + + to achieve saturation line monitoring.

Based on the engineering background of the belt conveyance roadway in the north wing of Zhuxianzhuang Coal Mine, this paper puts forward and analyses the existing problems in the optimization of the roof roadway location in upstream mining, and studies the movement law of overlying strata under different mining heights by FLAC3D numerical analysis software. On this basis, the orthogonal test is used to analyze the optimization of different location of roadway in overlying strata, determine the weights of three factors affecting the selection of roadway location, and put forward a reasonable roadway location for belt conveyance roadway in the north wing of Zhuxianzhuang Mine. According to the occurrence and use of surrounding rock of belt conveyance roadway in North Wing of Zhuxianzhuang Mine, two schemes of zonal support are put forward. Industrial test shows that the support effect is greatly strengthened and the support condition is improved, which can be used as a reference for the location selection of coal mine roadway and surrounding rock control under similar geological conditions.

This paper takes Zhuxianzhuang Mine as the research background. In this research, the reasonable height of “three zones” of overlying strata at 7m mining height is determined by key strata theory, and the movement law of overlying strata is studied by FLAC3D numerical simulation. The stress, displacement and plastic zone of surrounding rock under the three schemes of no support, bolt support and roof support are compared and analyzed according to the site construction situation. On this basis, the regional treatment scheme is put forward. The test results prove that the adoption of staged process control technology and enhanced support technology can effectively control the surrounding rock deformation of overlying strata roadway, which is scientific and reasonable in technology and effective and feasible in construction.
