There are extensive collieries, and the other industries include cotton manufactures, calico-printing, hat-making, iron-founding, engineering and the manufacture of firebricks and tiles.
A large number of cotton mills furnish the chief source of industry; printing, dyeing and bleaching of cotton and calico, spinning and weaving machine making, iron and steel works, and collieries in the neighbourhood, are also important.
Cotton spinning and printing works, cotton-mill machinery works, dye-works and chemical manufactures, and neighbouring collieries maintain the industrial population.
The principal collieries in the state are the Outtrim Howitt, the Coal Creek Proprietary and the Jumbunna.
The canal once served 30 collieries in the 19th.
