The L\P instrument measures the rate of gas release frorn coal under standard conditions. The original development of the technique took place in the USSR and France for use as an indicator of a coal seam's susceptibility to gas outburst in underground operations. In Canada, the L\P technique was applied to coal degradation, oxidation and handling problems.This paper describes the development of a L\P instrument for industrial use. The original glass instrument was redesigned in order to automate control of the entire procedure and record experimental data by using a desk top computer. Principles of operation, instrument design and test procedure are detailed along with relevant data. Application of the L\Pdata for prediction of gas outburst propensity, handling, degradation and oxidation properties are discussed and compared with operating data and/or alternate predictive measurements. Emphasis is given to applications relevant to coal handling and preparation problems.
