The invention discloses a coal mine fault control degree evaluation method and system, and relates to the technical field of fault identification reliability evaluation. The method comprises the following steps: fusing a mining area feature set with a label set, and establishing a training set and a to-be-predicted set; constructing a support vector machine dichotomy model and training the support vector machine dichotomy model; inputting the test set into the trained model, outputting a posterior probability value P1 of each sample point, and determining a dynamic threshold according to the posterior probability value; mapping the posterior probability into the fault point category by using the dynamically determined threshold value, and evaluating the quality of the fault point; and evaluating the fault risk grade of an area with densely distributed fault points in the mining area through the proportions of the breakpoints with different qualities. According to the method, objectivity and high efficiency of AI can be maintained, and reliability quantitative evaluation capability of artificial experience can be recovered and even exceeded.

This invention provides a method for virtual digital lofting and real-time calibration of installation pose of a guide rail, comprising: providing at least two positioning fixtures, each fixture having three collinear optical markers symmetrically arranged on both sides relative to the center marker; fixing the two positioning fixtures to the upper and lower ends of the guide rail respectively, so that the positioning fixtures are in close contact with the two working surfaces of the guide rail; acquiring the global coordinates of all optical markers in real time through a motion capture camera array, and independently calculating the six degrees of freedom pose deviation of the guide rail based on a coordinate comparison scheme corresponding to the layout of the positioning fixtures: calculating the horizontal translation deviation of the upper end of the guide rail; calculating the tilt angle deviation of the guide rail in the vertical plane; calculating the rotation angle deviation of the guide rail about its own length axis by using the coordinate difference of the two markers on both sides of the same positioning fixture on a single coordinate axis; and making targeted adjustments to the installation state of the guide rail according to the calculated pose deviations of each degree of freedom, thereby completing real-time calibration.
