The ventilation process's main task is clearing the dust and various gases, which might pose a danger to the workers getting into the mine.. Some of the common gases that are cleared include NOx, carbon monoxide, diesel particulate, and radon gas.. The gases can result from the blasting and drilling happening in the mine or naturally come from the rocks.

Mines in Zambia. In total 22 mining leases were established during our study period (2000–2019) with the first new mine during this period commencing operations in 2004 (Fig. 1).This represents 3422 km 2 of new land under a mining lease (Fig. 1), (Sup Mat Figure S1).As pre-existing leases covered an area of 2334 km 2, the total area mined has more than doubled during the past 20 …
of Mining on Water Resources and implications to provision of basic needs of water and sanitation to the local communities is indeed daunting. The impacts are far reaching and the governance processes are yet in a state of denial and are indeed apathetic and at best complacent. Mining and allied industries are major guzzlers of water and biggest
extract the ore reserve estimated for that part of an orebody from the total mineral resource estimates. This subset from the total mineral resource estimates is termed Ore Reserve Depleted by Mining [4]. Having obtained this subset, the resource engineer is able to conduct direct comparison with grade control, mine output and processing results.

The conventional mine planning approach for shallow resources with considerable vertical or deep extension creates an optimal UPL as the initial step, then develops a production schedule for reserves within the UPL (Lerchs and Grossman, 1965; Caccetta and Giannini, 1986).Thus, it ignores the viability of the UG mining method for reserves within UPL.

From preliminary underground mining studies, a selective underground mining method known as long hole open stoping was identified as a potentially viable underground mining method. The production schedule for a combined open pit and underground mining scenario requires that both mining options compete for the same reserve during optimization.
