DOT – Decline Optimisation Tool

DOT, a software package which finds the least cost decline network serving an arbitrary number of underground access and draw points. A powerful productivity tool for underground mine design.

enter site DOT is a software tool for use by mine planning engineers to guide the design of a near-optimal (minimum cost) network of navigable declines in an underground mine servicing a given set of access and haulage points associated with an ore body. The source url DOT-generated decline template minimises development plus haulage costs.

opcje binarne bossa DOT finds a network of decline paths that avoids no-go regions specified by the user. It takes into account operational constraints such as decline gradient, turning circle radius, and straight sections of the declines near junctions. follow link DOT also determines near-optimal locations for breakouts of subsidiary declines in the network, given the network topology. binary 0 100 DOT can automatically select the best option for level access or best choice of breakout points where there are alternatives. click DOT returns centreline strings of the optimal declines, and a summary report showing the selected points, and the lengths, gradients, development and haulage costs, for each link in the optimal network.

enter site DOT includes a tool that allows the user to adjust any design generated by the program, by fixing selected breakouts and freeing others, and then rerunning the optimisation. DOT provides a facility for viewing a 3D rendering of the optimal decline network together with any barriers.

The design can be imported into standard general mine planning packages (such as Vulcan and Datamine) for viewing and further processing.

DOT uses a combination of dynamic programming, simulated annealing, and geometric optimisation techniques.
