An industrial machine and methods for providing automatic tilt control for the same. One method includes determining a current tooth vector of a tooth included on a bucket of the industrial machine and a current path vector of the tooth and determining a current digging angle between the current tooth vector and the current path vector. The method also includes determining a delta angle based on the current digging angle and a target angle and automatically adjusting a tilt of the bucket based on the delta angle.

The invention is directed to a method of strip mining that involves dividing the pit into blocks in a diamond shape arrangement with an angular advancing strike face and removing waste material from each diagonally adjacent block so as to minimize the amount of waste material pushed by dozers and maintain the incline of ramps to gradients of 10% or less so that trucks can take mined ore from the pit.

A work machine control system is configured to control a work machine that travels in an operation region and includes a position detection unit, a non-contact sensor, and a control unit. The position detection unit detects a position of the work machine. The non-contact sensor detects a position of an object around the work machine. The control unit extracts information on an object to be detected from a detection result of the position detection unit and a detection result of the non-contact sensor, and excludes moving object information that is information on an object to be detected regarding a moving object that moves in the operation region.

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.

A method for quickly optimizing key mining parameters of an outburst coal seam as provided includes steps of constructing a graphic basic information model of the coal mine, giving coal mine characteristic information, performing mining simulation, constructing a CNN-LSTM predicating model, obtaining changes under different mining conditions, constructing a Lorenz chaotic primer, and the like. The model can be improved with continuous breakthroughs in theory, so that the model has a strong learning ability and can adapt to the constantly changing complex geological environment. The method has very good predictability for the determination of coal seam group parameters, and can efficiently select and output a set of candidate parameters.
