A mining simulator is a type of simulation used for entertainment as well as in training purposes for mining companies. These simulators replicate elements of real-world mining operations on surrounding screens displaying three-dimensional imagery , motion platforms , and scale models of typical and atypical mining environments and machinery.
System Locked Pre-installation (SLP), also referred to as OEM Activation, is a product activation procedure for Microsoft Windows used by major OEMs of laptops and pre-built PCs wherein a Windows product key is added and locked to the machine's firmware before mass distribution. SLP product keys cannot be moved to other machines.
A dockable PC is allowed three extra changes beyond a non-dockable PC before reactivation is required. The verification data is also based on the product key entered during activation. In some cases, the product key is checked against a list of known illegally distributed keys. [27]
For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. [1] The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverized coal is a significant dust explosion hazard, as large quantities are suspended in air ...

Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal’s intended application (e.g. steam generation, coking). [1] The quality attributes that are most important in blending will differ from one mine site to another and also depend on how the coal seams vary in ...
