Abstract (en)
[origin: WO9532357A1] In a process for establishing the starting point for gas extraction drillings in a tectonically stressed coal seam, the aim is to improve safety with an economical establishment of the starting points. To this end, the drillings are made in tectonically determined regions in which gas is very likely to be present and with an adequate gas circulation, in which, besides the underlay, the run and the hade of the faults, account is taken of the dispersions, creasing and pressures and the tectonic mass transport influenced thereby as bases for planning.
