摘要：

The efficacy of a mixture of ammonium nitrate prills, sawdust, fresh diesel and used oil (engine oil, hydraulic oil, transmission oil etc.) as. an efficient explosive was investigated in a limestone mine of Adhunik Cement Limited at Jaintia Hills in Meghalaya state of India. An air-decking column of 1 m length wooden spacer was used in each blasthole. The method was proved well effective in not only improving the blasting performance but also reducing cost of blasting. It is anticipated that this method will open up an effective approach to utilization of waste materials like sawdust and used oil in blasting operation.
