 In last years in Polish coal mining industry special attention has been paid to the environmental protection. The disposal of coal combustion products (CCP-s) and mine waste represents capital and operating cost to mining operation. Waste fill used in Polish coal mines have evolved from early dumped rocks and hydraulically or pneumatically placed crushed rocks up to today’s hydraulically transported, densified and cemented fills with fly ash and flue-gas desulphurization by-products.
