The present invention relates to a CPR posture monitoring model and system, the model being configured to: based on human skeleton point data extracted from CPR moves, at least compute arm-posture angle data and GC matching angle data related to the CPR moves, and determine whether the CPR moves are qualified by comparing arm-posture angle data and GC matching angle data to a CCP qualification threshold; wherein human skeleton point data are extracted from first move data collected by a first optical component and second move data collected by a second optical component simultaneously, wherein an included angle between collection directions of the two optical components ranges between 30 and 90 degrees. By constructing and applying a CPR posture monitoring model defined by data like GC matching angle, evaluation result has higher accuracy. Compared with the prior art where the equipment positions must be exactly the same as the equipment positions when the data are acquired for the AI algorithm to compute the CPR mistakes, the disclosed method does not require that the equipment positions must be exactly the same as the equipment positions when collecting the data and could tolerate inaccuracy or error in the equipment positions, besides, the disclosed method could realize harmless quality control of CPR moves.

The present disclosure provides a substrate, a maintenance method thereof and a display device. The substrate includes a base substrate, the base substrate is provided with at least one conductive pattern, and at least one of the at least one conductive pattern is interrupted and divided into a first conductive sub-pattern and a second conductive sub-pattern. The maintenance method includes: coating a conductive material in an interruption region in such a manner as to cover both the first conductive sub-pattern and the second conductive sub-pattern; and coating an organic insulation material at a side of the conductive material away from the base substrate, and curing the organic insulation material to form an organic protection film covering the conductive material.

Substrate, maintenance method and display device

A coal mining method is provided without coal-pillar leaving and without laneway excavation in a full mining area. The coal mining method includes drilling a main shaft, an auxiliary shaft and a return air shaft from a ground to a coal mining layer; by a coal mining machine, forming a first mining face with a first direction as an advance direction; by the coal mining machine, cutting out a first haulageway and a first return airway while cutting the coal wall at the first mining face, and preserving the first haulageway and the first return airway. In this method, the first haulageway and the first return airway are located on two sides of the first mining face, the first haulageway is in communication with both of the main and auxiliary shafts, and the first return airway is in communication with the return air shaft.

Method for coal mining without reserving coal pillar and tunneling roadway in whole mining area

An underground longwall mining method includes drilling a main shaft and an auxiliary shaft from a ground to a coal bed and exploiting in the coal bed first and second connection laneways. The first connection laneway is in communication with the main shaft, and the second connection laneway is in communication with the auxiliary shaft. The method further includes communicating the first and second connection laneways, and using a communication part between the first connection laneway and the second connection laneway as a first open-off cut; and by using a direction of the first open-off cut further away from the connecting line connecting the main shaft and the auxiliary shaft as a first direction, and exploiting by cutting a coal wall in the first direction using a coal mining machine.

Underground longwall mining method
