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 …
Merge mining exacerbates this issue, as the additional investment required to set it up means that fewer and fewer independent nodes are capable of adjusting to it. Additionally, with the increase of external hash power that comes with merged mining, mining difficulty increases and mining payouts become smaller for the auxiliary chain-focused ...
Combined mining is when two working faces separated by a certain distance simultaneously advance in the same direction, which commonly results in stress concentration and rockburst. This paper ...
Methods: The proposed approach combines a text mining (TM) procedure and integrative systems biology to comprehensively analyze the scientific literature to enrich AOPs related to environmental stressors. First, to identify relevant associations between BPS and different AOP components, a list of abstracts was screened using the developed text ...

In the process of the surface-underground combined mining, the fracture development of strata has important influence on layout of roadways and stability of the mining slope. Based on a pratical ...
Enterprise data mining applications often involve complex data such as multiple large heterogeneous data sources, user preferences, and business impact. In such situations, a single method or one-step mining is often limited in discovering informative knowledge. It would also be very time and space consuming, if not impossible, to join relevant large …
