Extraction machine for underground ore extraction operations and a method of extracting output products in underground ore extraction operations

A method for the extraction of ore products in underground ore mining operations using blasting in the face with the employment of an advancing support equipment and a face conveyor coupled to it and with at least one boring device for the production of shot holes and a loading device for the loading of the face conveyor with the blast rock loosened by blasting whereby the boring device and the loading device can be connected or are connected to a common boring and loading machine travelling along the face conveyor at right angles to the direction of mining, with the following steps in which:

• shot holes are bored in the rock face at right angles to the direction of mining and essentially parallel to the longitudinal direction of the face using the boring device connected to the boring and loading machine;
• the boring and loading machine together with the boring device is driven back along the face conveyor to a safe distance from the firing point and re-equipped with the loading device whilst the preparations for firing are made;
• following completion of firing the boring and loading machine, equipped with the loading device is driven forward, in order to load the loosened blast rock onto the face conveyor running parallel to the path of the loading machine;
• the boring and loading machine with the loading device is then driven back and re-equipped with the boring device;
• the boring and loading machine, equipped with the boring device is driven forward and repetition of the previous steps in the method are continued until the mining of the entire length of the mining is complete;
• and
• the support equipment together with the face conveyor is then advanced.
