Abstract: The present disclosure provides a coal bump control method for sectional hydraulic fracturing regions of a near vertical ultra thick coal seam. The method includes: deepening a main shaft from a mining level to a fracturing level; excavating a cross-hole from a roof rock layer of a coal seam at the fracturing level to enter a coal seam being mined, and excavating a roadway along the strike of the coal seam; and drilling hydraulic fracturing boreholes in a dedicated fracturing roadway along an inclination angle of the coal seam to the coal seam above the roadway, wherein the length of the borehole makes the borehole in communication with a goaf, and the spacing of the boreholes along the strike and the sectional spacing of the boreholes in an inclination direction are designed according to the parameters of fracturing equipments and the fracturing length.

Abstract: The present invention provides an image identification method, a magnetic resonance imaging method and an imaging apparatus. Said imaging apparatus comprises: a scanning device configured to scan a target object to obtain projection images of the target object along different directions; a processing unit configured to process the obtained projection images to obtain posture feature information of the target object; a posture determining unit configured to determine a posture of the target object according to the obtained posture feature information. Therefore, the posture of the target object may be automatically recognized during the imaging, and thus the imaging operation is simplified, improving efficiency and reliability of the imaging operation.
