    摘要： Disclosed is a method for the controlled maintaining of a mechanically favorable distance (33) between the roof and the face in longwall coal mining operations comprising a face conveyor (20), at least one extraction machine (22), and a hydraulic shield support. In said method, the inclination of the top canopy (13) and the floor skid (11) in the mining direction is determined by means of inclination sensors (17) mounted on at least three of the four main components of each shield support frame (10), such as the floor skid (11), the gob shield (14), the supporting connection rods (16), and in the gob zone of the top canopy (13), the effects on the distance (33) between the roof and the face are determined in a computer unit on the basis of the measured data when the angle of inclination of the top canopy (13) changes, and the parameters that are crucial for the working cycle of the shield support frame (10) are automatically adjusted, said working cycle consisting of a retracting, advancing, and setting process.

    摘要： The invention relates to a method and to a device for monitoring the track of a cutting extraction machine (1), which is used in particular in coal mining and can be displaced during longwall mining in a longwall face equipped with face conveyors (9) and longwall advancing (12, 13) along the face (10). The underlying object of the invention is to create a method and a device which make it possible, despite extremely poor visibility conditions, for example in the track of the extraction machine, to detect present obstacles in the form of lowered canopies or drooping folding canopies, sliding canopies or other additions to the lining or overloads of the conveyor in order to take measures for avoiding interruptions in the operation in a timely manner. In order to achieve this object, according to the invention the track of the extraction machine (1) is scanned using a radar measuring device (14) associated with the extraction machine (1) and upon detection of an obstacle an alarm is triggered and/or an invention in the controller of the extraction machine (1) takes place.

    摘要： The invention relates to a rock drilling rig and a method of positioning a rock drilling unit. The rock drilling rig (5) is provided with a detection device (4) for detecting a reference line (RL), such as a previously drilled drill hole fan (1). The detection device is positioned in the direction of gravity (G). The position and direction of the detected reference line are utilized when positioning a drilling unit to a new drilling position at a predetermined horizontal reference distance (RD) from the reference line.
