English title: Observations on the removal of stones in drain digging of peatlands

Abstract

Stones can be removed in drain digging of peatlands by using explosives or hoisting devices. The report is based on observations, and time and motion studies on drainage sites in the state forests in Northern Finland in 1931‒1933. Dynamite has been previously the most common explosive used in drainage sites. The new explosives containing potassium chloride proved to be cheaper, and safer to handle and transport than dynamite. According to the time and motion studies, the use of hoisting devices to lift stones that are removable, was significantly cheaper than explosives.
