Abstract

Zgłoszenie dotyczy sposobu wzmacniania górotworu dla projektowanego wyrobiska chodnikowego w górnictwie podziemnym, zwłaszcza węgla kamiennego. Z istniejącego wyrobiska (2) wierci się wokół obrysu projektowanego chodnika (1) równoległe na jego wybiegu względem osi wzdłużnej (O) osłonowe otwory iniekcyjne (4), o długości (L) i przez nie następnie zatłacza się środki wiążące, których wytrzymałość na ściskanie po zżelowaniu jest większa od wytrzymałości na ściskanie skał otaczających (3), a w końcu drąży się chodnik (1). Wzmacnianie skał otaczających (3) może być realizowane odcinkami, gdy na wybiegu występują skały otaczające (3) o zmiennej wytrzymałości na ściskanie. Na końcach odcinków (L) wykonuje się korzystnie zamykające otwory iniekcyjne (6) w płaszczyźnie prostopadłej do osi wzdłużnej (O) chodnika (1) i zatłacza się przez nie środki wiążące.The application concerns a method of strengthening the rock mass for the planned heading excavation in underground mining, especially in hard coal mining. From the existing excavation (2) around the outline of the designed gallery (1) parallel, on its extension to the longitudinal axis (O), protective injection holes (4) of length (L) are drilled, and binding agents whose compressive strength are injected through them after gelling, it is greater than the compressive strength of the surrounding rocks (3), and finally the gallery is drilled (1). The strengthening of the surrounding rocks (3) can be carried out in sections when the surrounding rocks (3) with variable compressive strength are present in the runway. At the ends of sections (L), closing injection openings (6) are preferably made in a plane perpendicular to the longitudinal axis (O) of the roadway (1) and binders are injected through them.
