The construction of the largest coking coal mine in OKR started in 1962 under the name of Staříč Mine. The mine is located in the southernmost part of the Ostrava-Karviná district in the Staříč mining area, which is 42.5 km2 in size. The first tonne of coal was mined in 1971 and full projected production was achieved in 1980, when its construction was completed.
In 1994, the Staříč Mine, consisting of the Sviadnov, Staříč and Chlebovice sites, merged with the Paskov Mine. In 1999, it was decided to close the Paskov plant and transfer it to the branch Odra Mine. The original Staříč Mine remained in operation under the name of Paskov Mine.
Hard coal mining was definitively terminated on 31 March 2017. On 1 January 2021, Paskov Mine was transferred to the state enterprise DIAMO, branch DARKOV.
The highest annual production was reached in 1988, namely 1.45 million tonnes of coal. From the start to the end of mining, 46.6 million tonnes of coking coal were extracted from the Staříč Mine.
The reserves of the Frenštát Mine consist of two deposits: Frenštát-západ and Frenštát-východ. The Frenštát Mine Plant is located in the Trojanovice mining area, which covers an area of over 63 km2. Together with the neighboring Čeladná-Krásná exploration area, it is the only significant coal deposit with recoverable seams of the Karviná Formation outside the Karviná region. There are five seams suitable for use. In addition, there is also the Ostrava Formation.
Exploratory boreholes drilled from the surface in the late 1960s and early 1970s proved the extensive occurrence of the Karviná Formation in the Frenštát area. On this basis, it was decided to continue the exploration by digging mining works in the final profiles.
In September 1984, the excavation of the shaft 4 of the projected Frenštát-západ plant began, but during the work the shaft reinforcement collapsed and the shaft caved in to a depth of 660 m from the shaft bank. The reconstruction of the shaft was carried out with reinforced reinforcement. Excavation of the shaft to a total depth of 903 m was completed in June 1994.
In September 1985, the excavation of the shaft No. 5 began in the same location. The two shafts were connected at the level of -442 m.
The construction of the projected Frenštát-sever plant, located in the cadastral territory of the Tichá municipality, which was to be the mining centre of the Frenštát Mine, did not take place (only the excavation of shaft No. 2 with a clear diameter of 8.5 m to a depth of 8 m was carried out), because in 1991 the construction of the Frenštát Mine was interrupted and the transition to the conservation regime was initiated. In 1991, exploration drilling was still being carried out in the mining area, but construction work on the mine itself was stopped (except for the completion of Shaft 4 in 1994).
In 1995, it was decided to switch the Frenštát Mine to a conservation regime, which has been in place ever since.
