The article presents the analysis results of scientific and technical literature and other sources information on soil pollution during accidents at pipeline transportation facilities. The gas supply system of Ukraine is a complex energy system characterized by long length, significant power, complex structure, different age and state of the main gas pipelines. The aging of gas pipelines, a large number of accidents, failures and damage to the linear part complicate the maintenance process of the gas transportation system and increase material costs. In these conditions, the improvement of environmental safety to prevent accidents, the uninterrupted supply of natural gas, reduction of losses and negative impact on the environment are relevant issues. It has been established that with a gas pipeline laying depth of 1.5 m the concentration of harmful substance on the top of the ground is almost zero. In addition, the mathematical model makes it possible to estimate the impact area of the harmful substances source on the entire studied territory with one or several pipelines. The performed calculations are of a test nature. To study the real emergency situations, it is necessary to have information about the following factors: the speed of measures on the fault section disconnection; physical and mechanical parameters of soils; working pressure in the pipeline system. The proposed mathematical model will make it possible to analyze the spread of emergency leaks products depending on the location of emergency leaks of natural gas, properties of soils, speed of response and spread of an emergency situation
