摘要

Usage: The invention relates to mining, in particular to methods .krepleni generation in conditions burial inclined coal seam. SUMMARY: determining the depth (thickness) zone delamination sawmills h and layering N and then with N 2 set anchor with the hp and effective length embedment anchor angle p a / 2, where a - angle of incidence of the formation to the normal of the formation into the uprising reservoir , in the presence of a multi-ply roofing (N 2) with the gauge length and hp embedment anchor establish two anchors, one .From which is normal to the reservoir, and the other - vertikalno.2.il.
