The „Belchatów“ Brown Coal Mine (KWB) runs an open cast mining of brown coal field located in the central region of Poland. The KWB has an annual production capacity of 38,5 million tons of brown coal. The mine was built by applying many original and innovative technical solutions and now is reckoned as one of the most modern and biggest open cast mines in Europe and worldwide. In 2002 a new deposit „Pole Szczerców“ mining has begun. The fiber optic technology and RS2 switches by Hirschmann™ are used there to connect automatic and security systems.
