Abstract

Przedmiotem wynalazku jest sposób odmetanowania górotworu zwłaszcza w kopalniach węgla, polegający na wykonaniu otworów odmetanowujących z chodników przyścianowych w rejonie ściany, charakteryzujący się tym, że z tych chodników (1) drąży się dodatkowy chodnik (2) o długości od 2 do 10 m służący do zabudowy hydrauliczno-płuczkowej napędowej jednostki wiertniczej (3), a następnie z czoła przodka (4) wykonanego dodatkowego chodnika (2) nawierca się za pomocą tej jednostki przynajmniej jeden otwór (5) w skale płonnej (6) na 300-tu metrowy odcinek frontu ściany (7) w kierunku tej ściany, na dowolnym wybiegu, po czym nawiercony otwór (5) poddaje się rurowaniu za pomocą rur (8) lub pozostawia bez rurowania, a następnie kanał utworzony z tych rur (8) lub nawiercony otwór (5) wypełnia się nieściśliwym materiałem przepuszczalnym np. żwirem.The subject of the invention is a method of methane drainage of a rock mass, especially in coal mines, consisting of making drainage holes from wall sidewalks in the wall area, characterized by the fact that from these sidewalks (1) an additional sidewalk (2) with a length of 2 to 10 m is drilled hydraulic drilling mud drive unit (3), and then from the face of the face (4) of an additional pavement (2), at least one hole (5) in the gangue (6) is drilled using this unit for a 300-meter section of the front walls (7) towards this wall, on any runway, after which the drilled hole (5) is piped with pipes (8) or left without piping, and then the channel formed from these pipes (8) or the drilled hole (5) it is filled with compressible, permeable material, e.g. gravel.
