Jan 08, 2021· Process mining sits at the intersection of business process management (BPM) and data mining. While process mining and data mining both work with data, the scope of each dataset differs. Process mining specifically uses event log data to generate process models which can be used to discover, compare, or enhance a given process.
Nov 10, 2020· In addition to being safe and efficient, precision surface mining methods are helping miners create better sustainability practices. The vibrations caused by blasting can damage nearby infrastructure, including roads, utility lines, pipelines and buildings. To avoid this, mines are forced to abandon areas within close proximity to these obstacles.

stone is processed. Kabul and Herat each process about 300 metric tons/month (t/m). Herat, which has nine factories, produces a white stone of very good quality. Kabul, with 13 factories, produces white, black, and green colored stone. Kandahar and Jalalabad produce …
This process is when a mining crew, after a rocks fracture, breaks down the fragments for transport. This is done by using a dedicated ship's extraction beam which will automatically breakdown the fragment and simultaneously moves the rubble to its storage bay. If the FPS mining technique was used, this process is done by simply moving the ...
A foremost element of the mining process is breaking up the rock. This breakup is accomplished by detonating volatiles set in blast holes. The rock face to be gusted is typically 40-feet in width by 20- to 25-feet high. A premeditated pattern of 40 to 50 horizontal holes are drilled for the dimensions of 2 inches wide by 12- to 14-feet deep.
A method for rubblizing an oil shale deposit that has been formed in alternate horizontal layers of rich and lean shale, including the steps of driving a horizontal tunnel along the lower edge of a rich shale layer of the deposit, sublevel caving by fan drilling and blasting of both rich and lean overlying shale layers at the distal end of the tunnel to rubblize the layers, removing a ...

The process described above has been with reference to a multiple hole solution mine. It is equally applicable to single bore hole mining with concentric pipes. In that case, the inner concentric pipe must be lowered to near the bottom of the rubble bed. The process described above was directed to mining a single KCl rich stratum.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
