Embodiment Construction

[0042] Hereinafter, the present application will be described in detail with reference to the drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0043] The current method of artificially controlling coal caving does not conform to the development trend of intelligent fully mechanized caving mining in extra-thick coal seams and the innovation direction of automated and unmanned coal technology advocated. Aiming at the problems existing in the existing coal-drawing methods, the traditional coal-drawing process is optimized and innovated by making full use of the existing intelligent control system, coal gangue identification technology, and classic coal-drawing theory in the fully mechanized caving face. This embodiment provides a special Intelligent group coal caving platform in fully mechanized caving face in thick coal seam, such as fi...

Abstract

The invention discloses an intelligent group coal drawing platform and method of super-high coal seam fully mechanized caving faces, and relates to the technical field of coal mine underground mining.The intelligent group coal drawing platform and method of the super-high coal seam fully mechanized caving faces is suitable for super-high coal seam intelligent fully mechanized caving mining condition, the top coal recovery rate is improved, the mixed rate of coal and gangue is reduced, the productivity is improved, and the automation degree is improved. The intelligent group coal drawing method of the super-high coal seam fully mechanized caving faces comprises the steps that a plurality of groups of fully mechanized caving face brackets contained by the intelligent group coal drawing platform are divided into main drawing bracket groups and auxiliary drawing bracket groups according to odd-even number, and each group of brackets comprises coal drawing brackets with predetermined number; the adjacent two groups of main drawing bracket groups are controlled to synchronously draw coal, the auxiliary drawing bracket groups are controlled to be lagging behind two groups of the main drawing bracket groups to perform adjacent two groups of synchronous coal drawing, during each group bracket coal drawing operation, a middle frame coal drawing opening is controlled to be opened fully,and two side frame coal drawing openings adjacent to the middle frame are opened half to disturb coal bodies; and during single group bracket coal drawing operation, all coal drawing openings of the single group bracket are closed immediately after a coal gangue boundary is recognized.

Description

technical field [0001] The application relates to the technical field of underground mining in coal mines, in particular to an intelligent group coal caving platform and method for a fully mechanized caving face in an extra-thick coal seam. Background technique [0002] Coal is the country's main energy source, and extra-thick coal seams are rich in reserves, and fully mechanized caving mining methods are mainly used. The realization of safe and efficient mining of extra-thick coal seams is of great significance to ensure the country's continuous supply of coal. At present, "accelerating the development and application of unmanned coal mining technology" has been listed as a key project in the energy field, and the special action of "replacing people with mechanization and reducing people with automation" has pointed out the direction for technological innovation in the coal industry. The realization of intelligent fully mechanized caving mining in coal seams has become an i...
