Производство кукурузы на зерно связано с образованием большого количества биологической массы, которая после уборки урожая остаётся в поле в виде надземной сухой массы растения и подземной мощной корневой системы. Количество растительных остатков на гектаре после уборки кукурузы на зерно достигает 10-15 тонн. Для подготовки такого поля к дальнейшей эксплуатации необходимо подготовить пожнивные остатки кукурузы к процессу деструкции. Рассмотрены технические средства механической обработки пожнивно-корневых остатков кукурузы отечественного и импортного производства с анализом конструктивных особенностей рабочих органов. Ключевые слова: кукуруза, стерня, измельчитель, барабан, нож.

The methodological approach is based on an expert method, the use of which allowed the authors to create the structure of the risk management system and, determine the plurality of criteria parameters while taking into account their weight in the formation of the environmental consequences of chemical accidents. Criteria parameters were grouped into clusters of physicochemical and toxicological properties of hazardous chemicals used at a chemical plant, equipment operating at an enterprise, personnel, and environmental vulnerability. The research became the basis of the Guidelines for Assessing the Environmental Risk from Emergencies at Chemically Hazardous Sites. As an example, the article presents the calculation of the level of environmental risk for a terrestrial site from the metallurgical enterprise LLP Kazakhmys Smelting, in Zhezkazgan town, Republic of Kazakhstan. The developed methodology is the basis of the Information and Analytical System for Assessing the Environmental Consequences of Man-made Emergencies, which allows users to facilitate the implementation of a set of measures aimed to forecast and reduce the impact of emergency's damaging factors on the environment.

This system’s implementation will make the industrial safety management at industrial sites more effective. Multifactorial, probabilistic, determined models of accidents’ hazard and severity indexes are integrated into the computing core of the Information and Analytical System. Then, statistical methods determine the risk assessment of occupational injuries and diseases. The <em>Information and Analytical System for Hazard Level Assessment and Forecasting Risk of Emergencies in the Republic of Kazakhstan</em> allows users to work efficiently with large volumes of information and form a united analytical electronic report about the state of industrial safety. The main objective of the monitori...

Methods: Risk assessment of accidents and incidents is based on expert evaluations. Based on the lists of criteria parameters and their possible values, provided by the experts, a unified information and analytical database is compiled, which is included in the final interrogation questionnaires. Risk assessment of industrial injuries and occupational diseases is based on statistical methods. Results: The result of the research is the creation of Guidelines for risk management on hazardous industrial sites of the Republic of Kazakhstan. The Guidelines determine the directions and methods of complex assessment of the state of industrial safety and labor protection and they could be applied as methodological basis at the development of preventive measures for emergencies, casualties, and incidents at hazardous industrial sites. Conclusion: Implementation of the information-analytical system of risk level assessment allows to analyze the state of risk of a possible accident at industrial sites, make valid management decisions aimed at the prevention of emergencies, and monitor the effectiveness of accident prevention measures.
