The article presents the theoretical and practical research results regarding the development of the IT and methodological infrastructure for assessing the parameters which define explosive substances. The software us intended for estimating, based on the chemical composition of substances, parameters which define such substances (detonation velocity, detonation energy, detonation pressure etc.), as well as for determining the probability of explosion. EXPLO5 is a specialized software which allows to solve thermo-dynamic equations between different reaction products in order to determine the balance composition, having incorporated a filtering algorithm for estimating Jones-Wilkins-Lee (JWL) state equations coefficients which are used for calculating the detonation energy of explosives. For the proper performance of pilot tests of numerical simulations upon certain representative types of explosives (civil use explosives and double-use explosives: civil and military) there have been taken into account the special characteristics of EXPLO5 provided by the EOS BKW (BKW standard with set of BKWN constants and BKW EOS modified with the set of constants and volumes BKWN-M) and EXP-6 EOS function which is based more on theoretical concepts.
