The invention relates to mining and can be used at prediction of outburst dangerous zones of coal beds at implementation of mining works. The method includes drilling of survey wells, compilation of hypsometric maps by data of survey drilling and following implementation of mining operations. In process of implementation of mining operations one carries out operation additional survey of coal bed and with use of data obtained one calculates and compiles volumetric surface of relief of bedding of coal bed, by signs of main curvatures of relief one separates there convex, concave and seat-like sections, with formation of map of geometrical sum of main curvatures of relief as criteria of complication of those within boundaries of mine field, one determines dangerous values of complication Кon worked out before sections with different form, with separation of potentially dangerous zones in which geometric sum of main curvatures of relief of bedding of the seam in point under consideration is К≥К. Use of the method for prediction of outburst-dangerous coal beds provides reliable determination of placement of abnormal zones of increased manifestations of natural (tectonic) origin, this makes it possible to increase effectiveness and safety of coal production. |
