EVRAZ to Produce More Coal at Raspadskaya-Koksovaya Mine
5 April 2019 (09:22)
UrBC, Yekaterinburg, April 5, 2019. EVRAZ Holding’s Raspadskaya-Koksovaya Mine adopted a new coal-extracting technology, the holding’s press service reports.
The company’s miners switched from the chamber-and-pillar method to the coal face technology, which is expected to boost the mine’s production output by 2.5 times.
The first jobs in preparation for the coal face launch began as early as last February. The miners went through the project documentation, set up a new mining section, and did 6 km worth of excavation work. Long-Face 3-2-1 (bis) has 886,000,000 kg in estimated reserves of valuable K coal type, is 225 meters long, and will produce up to 150,000,000 kg of coal every month.
To ensure miners’ safety, exhaust wells were made for the harmful mine gases, a centrifugal gas-suction/ventilation unit got installed in the mine, and a portable methane-removing unit is being assembled to avoid accidents at rock cavity. Besides, steps are being taken to make sure the coal does not start self-heating.
Raspadskaya-Koksovaya’s team are also working to get Long-Face 3-3-1 (bis) ready; the mine has estimated coal reserves of 1,058,00,000 kg. The air tracks are almost ready, and the installation chamber will get in place in June. The coal face is scheduled for launch in November 2019.
Raspadskaya-Koksovaya has no intention of giving up on the chamber-and-pillar method altogether. The miners will resume using the method during the face transfer periods to avoid downtime.
