A coal mining method is provided without coal-pillar leaving and without laneway excavation in a full mining area. The coal mining method includes drilling a main shaft, an auxiliary shaft and a return air shaft from a ground to a coal mining layer; by a coal mining machine, forming a first mining face with a first direction as an advance direction; by the coal mining machine, cutting out a first haulageway and a first return airway while cutting the coal wall at the first mining face, and preserving the first haulageway and the first return airway. In this method, the first haulageway and the first return airway are located on two sides of the first mining face, the first haulageway is in communication with both of the main and auxiliary shafts, and the first return airway is in communication with the return air shaft.

A method, device, and system for managing a mining facility including a plurality of systems. The method includes generating, on a simulation unit, system models for one or more systems from the plurality of systems of the mining facility. The system models are generated based on one of input signal, sensor data and output signal from the plurality of systems at the mining facility. The method further includes generating a facility model of the mining facility based on dependencies between the system models and managing the mining facility by simulating operation of the mining facility using the facility model.

A process and associated system for the improved reclamation of disturbed lands (e.g., mined lands) is disclosed. In particular, the system including a dewatering cyclone, a screw classifier, and a dewatering apparatus (e.g. a dewatering belt) arranged in series to enable rapid and cost effective dewatering of slurries containing dilute clay and sand tailings to create an improved engineered reclamation material (ERM). The ERM formed by the controlled combining of dewatered sand tailings with dilute clay slurry and with a flocculant and overburden. The ratio of clay:sand:overburden of the ERM may be achieved by balancing the solid content (Cw) and water content (1-Cw) materials of the clay slurry, sand tailings and overburden. In some embodiments, the system may include at least one additional component, such as, for example, static screen(s), centrifuge(s), vibrating screens, drum screens, belt screens, belt filters, and/or other liquid-solid separation devices.

A method of open cut mining comprising carrying out mining operations in an area of an open cut mine with manned resources and unmanned resources and providing separate access for these resources to the mine area at selected locations. Alternatively, or in addition, the method comprises carrying out mining operations in the mine area with manned resources and unmanned resources operating in selected, separate unmanned and manned zones, respectively within the mine area.

A method for providing a mining work machine at a work site with production control information, the method including: assigning, on the basis of overall production management information of the work site, the mining work machine with production control information, defining tasks to be performed by the work machine; downloading the control information to a mobile terminal from one or more downloading points associated with a production management system, the mobile terminal and the one or more downloading points including an application for mutually synchronizing desired control information; providing the mobile terminal in a vicinity of the mining work machine, the mining work machine further having an application for mutually synchronizing desired control information; performing an authentication between the mobile terminal and the mining work machine; selecting the control information to be downloaded to the mining work machine; and downloading the selected control information to the mining work machine wirelessly.

A includes a control arm comprising a first link and a second link, a lift arm articulately connected to the first link by a first joint and a first actuating means articulately connected to the first link by the second joint. The second link and the lift arm are adapted to permit a pivotal connection with a loading means by a third joint and a fourth joint, wherein the lift arm is adapted to lift and lower the loading means and the first actuating means is adapted for actuating the control arm, by acting on the first link in at least a direction from the first actuating means, to achieve a rotational movement of the loading means around said fourth joint, when the loading means is connected to the control arm and to the lift arm. During action of the first actuating means on the first link in the direction from the first actuating means a decrease of a distance between the second joint and the third joint is achieved.

The invention relates to a milling machine having a replaceable milling drum, different types of milling drums being capable of being associated with the milling machine; and having a control unit for controlling the milling machine, machine parameters of the milling machine being settable by way of the control unit. Provision is made that the milling machine has associated with it at least one means that is designed to detect at least one characteristic feature of the milling drum; that the at least one means is connected to the control unit; and that the control unit is designed to specify for at least one machine parameter, indirectly or directly from the characteristic feature, a value to be set, and/or a setting range. The invention further relates to a corresponding milling drum and to a corresponding method. The milling machine, milling drum, and method allow the selection of machine parameters for operation of the milling machine to be simplified.
