The Ulyanovskaya Mine disaster was caused by a methane explosion that occurred on March 19, 2007 in the Ulyanovskaya longwall coal mine in the Kemerovo Oblast. At least 108^[1] people were reported to have been killed in the blast, which took place at a depth of about 270 m (885 feet) at 10:19 local time (3:19 GMT). The mine disaster is Russia's deadliest in over a decade.^[2] Kemerovo Oblast governor Aman Tuleyev said that when the blast occurred, "the mine was preparing to launch an advanced mining safety system developed in the UK. The system signaled a sudden discharge of a large amount of methane and caving at 14:30 local time." According to the Russian Prosecutor General's office, "the explosion occurred when equipment was being tested". The explosive agent is thought to have been either methane or coal dust, both of which are highly susceptible to spontaneous combustion. The main theory for the cause of the explosion is that it resulted from "a breach of mining safety".^[3] However, the mine operator has denied any connection between the explosion and the new equipment.^[3]

Among the dead was a British mining consultant, Ian Robertson, who worked for the Anglo-German company International Mining Consultancy. According to Russian sources, the company was involved in auditing the mine's coal reserves.^[4] He was accompanied by most of the mine's senior management, who had gone underground shortly before the explosion; the entire party was caught in the blast.^[5] The audit was reportedly being conducted in conjunction with the mine operator's planned initial public offering to raise cash for a $700 million investment programme. ^[6]

The operator of the mine is Yuzhkuzbassugol ("South Kuzbass Coal"), a half-owned associate of the Evraz Group conglomerate, which is Russia's biggest producer of deep-mined coal.^[7]^[2] The mine, which opened in 2002, is one of the newest pits in the Kuzbass coal-mining region of Siberia, with modern equipment made in the UK and Germany.^[3] It has been producing at an annual rate of about 1.5 million tonnes of coking coal concentrate.^[6] However, it appears to have retained its Soviet era name, from Vladimir Ilyich Ulyanov, better known as Lenin.

In the aftermath of the accident it was revealed that the mine had suffered "problems with equipment safety rules".^[8] It has also been anounced that 60 coal mines in the surrounding area were inspected for similar violations shortly after the disaster, and that the entirety of the nation's mines are to be inspected over the coming weeks.^[8]
