Most of the county is steep and mountainous, and particularly so in the southeast. There are numerous high peas. The Pujŏllyŏng and Kŏmdŏk Mountains (검덕산맥) pass through the county, which reaches its highest peak at Kŏmdŏksan.
Mining and electrical power are the chief local industries. There are deposits of copper, iron ore, lead, and zinc. Local crops include maize, soybeans, and potatoes, but cultivation is difficult due to the mountainous terrain.
