An analytical assessment of loading process for cutting elements of longwall cutter-loader

Author: K. Krauze

An analysis of available information and design for cutting elements of longwall cutter-loaders has indicated that an analytical analysis of its loading capacity is required.

An analytical method for assessment of worm cutting elements has been developed by establishing boundary conditions and appropriate relationships.

The method enables an effect of design and kinematic parameters on loading efficiency to be determined and the most favourable parameters for longwall cutter-loader and downstream machinery to be found.

Therefore, any problems related to mined coal loading onto longwall conveyors and retarding the mining progress due to longwall chocks can be avoided.

By knowing the loading capacity for cutting elements and necessary investment expenditures for longwall equipment the user can choose the most suitable solution.
