Description
Verfahren zum Sichern loser Gebirgsschichten im Bergbau. Die Erfindung betrifft ein Verfahren zum Sichern loser Gebir-schichten im Bergbau mittels vorgetriebener, bewehrter und verkitteter Bohrlöcher. Das Neue besteht darin, daß in die in die losen Gebirgschichten vorgetriebenen, bewehrten Bohrlöcher Mörtel eingedrückt wird. Dieser -Mörtel stellt nicht nur eine äußerst feste und dauernde Verbindung zwischen den Bewehrungen in den Bohrlöchern und den Gebirg:chichten her, sondern er dringt auch in die benachbarten -Hohlräume der Schichten ein, und kittet den losen Boden zu einem festen; clie Bergbauwerke umgebenden Mantel zusammen.Method for securing loose rock layers in mining. The invention relates to a method for securing loose rock layers in mining by means of propelled, reinforced and cemented drill holes. The new thing is that in the in the Reinforced boreholes are driven into loose rock layers with mortar. This mortar not only provides an extremely strong and permanent connection between the reinforcement in the boreholes and the mountains: build up, but it penetrates also into the neighboring cavities of the layers, and cement the loose soil to a solid; the mantle surrounding the mines.
Vom Inneren der Bergbauwerke aus werden i planmäßig und der Gebirgschichtung entspre- . chend Bohrlöcher vorgetrieben, welche bis zu einer genügenden Tiefe in die gelockerten Gesteinsmassen, z. B. i,o bis 2.o m tief eindringen. Diese Bohrlöcher werden dann zunächst mittels Druckwassers ausgespült und gereinigt, wobei gleichzeitig die erdigen Zwischenlagen der Gesteinschichten mit fortgewaschen werden. Alsdann wird in jedes ; Bohrloch ein mit Einkerbungen versehener Eisenanker eingelagert und anschließend flüssiges Zementmörtel eingedrückt. Dieser Mörtel dringt von jedem Bohrloch aus tief in alle Hohlräume der durchschnittenen Gesteinschichten ein, füllt hier sämtliche Adern und Poren schließend aus und kittet die eingelagerten Eisenanker untrennbar fest in die verfestigten Gebirgslagen ein. Auf diese Weise werden die Bergbauwerke mit einem meterstarken Eisenbetonmantel umgeben, mit dem sie einen zusammenhängenden einheitlichen Eisenbetonkörper -von größter Widerstandsfähigkeit bilden. -From the inside of the mines, i are systematically and the mountain stratification corresponding accordingly boreholes are driven, which are to a sufficient depth in the loosened rock masses, e.g. B. penetrate i, o to 2.o m deep. These drill holes are then first rinsed and cleaned using pressurized water, at the same time the earthy intermediate layers of the rock layers are washed away with. Then is in each; Borehole an iron anchor provided with notches embedded and then injected liquid cement mortar. This mortar penetrates from everyone Borehole from deep into all cavities of the cut rock strata, fills here all veins and pores are closed off and the embedded iron anchors are cemented inseparably firmly in the solidified mountain ranges. In this way, the Mines are surrounded by a meter-thick reinforced concrete jacket with which they one coherent, uniform reinforced concrete body - of the greatest resistance form. -
