Embodiment Construction

[0026] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] figure 1 It is a schematic flow chart of a multi-information fusion mining method for a coal mine intelligent working face in an embodiment of the present invention. The method of this embodiment is suitable for deep mining (underground mining with a depth greater than 600m), especially for coal mining at a deep coal mine intelligent working face. The intelligent mining working face has an intelligent network and abundant sensors, which can not only collect key equipment data in real time and realize control, ...

Abstract

The embodiment of the invention discloses a coal mine intelligent work face multi-information fusion mining method and system, and relates to the technical field of coal mining. Mining efficiency andsafety of mining of a work face can be improved, and the mining method comprises the steps of obtaining state information, collected by a sensor, of a coal mine underground mining site; judging a monitoring area where the sensor is located; according to the determined monitoring area, determining a mine mining key restraint factor associated with the monitoring area; according to the state information, collected by the sensor, of the coal mine underground mining site, calculating current state value of a coal mining key restraint factor, and according to the state value, determining a state value threshold interval of the current coal mining key restraint factor; according to the determined state value threshold interval, determining a control strategy corresponding to the state value threshold interval; and according to the control strategy, correspondingly controlling the mining state of the coal underground mining site. The method and device are suitable for deep coal underground mining.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a multi-information fusion mining method and system for an intelligent working face in a coal mine. Background technique [0002] In recent years, with the passage of mining time, the mining of coal resources in my country has gradually shifted to deep areas, and mining areas rich in shallow resources such as Shanxi, Inner Mongolia, and Shaanxi are also gradually facing the problem of deep mining. Domestic experts and scholars have long been committed to the research on the stability of surrounding rock in deep coal resource mining. However, due to the complexity of the migration law of surrounding rock in deep mining, a series of problems such as the appearance of strong mine pressure at the working face, large deformation of the roadway, and easy instability of the coal wall has not been fundamentally resolved. Contents of the invention [0003] In view of this, the embo...
