Schrämverfahren.
Beim Sehrämverfahren nach Patent Nr. 5969 müssen seitlich des Abbaustosses Strecken aufgefahren werden. Da nun Verhältnisse vorliegen können, welche ein Auffahren von Strecken nicht gestatten, so ist das Verfahren gemäss Patent Nr. 5969 nicht immer anwendbar. In solchen Fällen soll das Verfahren gemäss der Erfindung Verwendung finden.
EMI1.1
der Hauptstrecke A aus Durchhiebe b hergestellt, in welche das Schriimseil eingezogen und bewegt wird. Die Antriebsmaschine d wird für diesen Fall zweekmässig in bekannter Weise mit einer Vorschubvorrichtung versehen. Durch Bewegung des Seiles a wird alsdann der ganze Pfeiler 1, 2,3, 4 unterschrämt werden.
EMI1.2
diesen Fall wird der Pfeiler 1, 2, 3,4 seitlich abgeschrämt.
Soll endlich der Pfeiler allseitig abgcschr1. imt worden, um jegliches Hereinschiessen zu vermeiden, so werden, wie in der Fig. 3 dargestellt ist, drei Löcher g1, g2, g3, von etwa 30 cm derart gebohrt, dass sie mit einem Loch A, welches einen solchen Durchmesser haben muss, dass ein Mann hindurchkriechen kann, die vier Ecken eines Materialpfeilers S von viereckigem Querschnitt bilden. Auf der hinteren Seite dieses Pfeilers wird ein Raum B ausgebaut, in welchem die Arbeitsmaschine aufgestellt wird. Die mit Zähnen besetzten

Since conditions can now exist which do not allow driving on roads, the method according to patent no. 5969 is not always applicable. In such cases, the method according to the invention should be used.
EMI1.1
of the main line A made of cut-outs b, in which the crotch cable is drawn and moved. In this case, the drive machine d is provided with a feed device in a known manner. By moving the rope a, the entire pillar 1, 2, 3, 4 will then be undercut.
EMI1.2
In this case, the pillar 1, 2, 3, 4 is chamfered laterally.
Should the pillar finally be scribed on all sides. In order to avoid any shooting into it, three holes g1, g2, g3, of about 30 cm are drilled in such a way that they are connected to a hole A, which must have such a diameter, as shown in FIG. that a man can crawl through, forming the four corners of a material pillar S of square cross-section. On the rear side of this pillar, a room B is being built, in which the working machine is set up. Those studded with teeth
