The transition to mining benches with transverse panels from top to bottom within the boundaries of steeply inclined layers does not allow transforming the results of mininggeometric analysis sequentially for each individual stage of mining into a calendar schedule of mining operations. Therefore, a model is offered for converting the results of mining-geometric analysis into a calendar schedule of mining operations with sequential mining of benches from top to bottom using phased volumes of overburden rocks and o...

Ensuring the stability of underground construction remains a challenge in terms of coal mining. The implementation of effective coal mining technology facilitates high rates of operations and simultaneous exposure of large-scale rocks. This problem is relevant both for Ukraine, where underground coal mining is the main one and for Kazakhstan, where the transition to combined open-underground mining is also underway. Supporting the mined-out space under complicated geological conditions requires an in-depth analysi...
