The course deals with the issues related to the safety of work in mining activities. The main risks related to mining exploitation are analyzed, in order to be able to counteract them with a correct planning of the activities.
The course deals with the issues related to work safety in civil and mining activities. The main risks associated with civil works and mining exploitation are analyzed to counteract them with the correct planning of the activities. Analyses of notable examples and statistics from different construction site works will be made.
The course aims to provide students with information on the main causes of accidents or damage to the health of workers in quarries and mines and on the operational techniques aimed to reduce the risk, in order to be able to plan operations and activities in mining in a correct and safe way.
At the end of the course, students will be able to: - analyze the construction sites as working places; - identify the possible sources of risk for workers; - understand the leading causes of accidents or damage to workers' health in civil works, quarries, and mines and the operational techniques; - reduce and mitigate the risk of planning operations and activities
The fundamentals of applied geology, geomechanics, structural mechanics, excavation engineering and risk analysis are required.
Fundamentals of physics (kinematics, dynamic, static, electrostatics, and electromagnetic waves and fields), chemistry (elements and the periodic table, states, and stoichiometry), and continuum mechanics (analysis of strain and stress, constitutive laws and strength criteria, and geometry of areas); fundamentals of geomechanics applied to mining and underground construction (soil mechanical behaviour, theorems of plasticity theory, active and passive limiting states of stress and earth pressures)
1. General information on safety issues in quarries and mines 2. The organization of activities in quarries and mines; main sources of risk for workers 3. International legislation on safety in the mining sector 4. Analysis of occupational risks in mining; causes of accidents and strategies for the containment of accidents 5. Risk of accidents and damage to the health of workers resulting from dust, asbestos, radiation and electromagnetic pollution, from the radioactivity of rock formations 6. Risks related to poor lighting of underground environments 7. Risks linked to the particular conditions of the microclimate of underground spaces 8. Risks related to noise produced by mining machines and plants 9. Risks due to the fall or slipping of rock blocks from the profile of the underground voids; risks of collapse of the excavation face or of the heaps of the excavated material; the instability of mining landfills; the collapse due to buckling of support struts in underground cavities 10. Risks linked to the early activation of the mine blasting circuit, to the throwing of the shootted down material, to the presence of unexploded sticks after blasting 11. Risks related to the explosion of the mine atmosphere in the presence of inflammatory gas and explosive dust; risks of fires in confined environments.

The exercises will cover three different environments typical of mining activities: an open pit, an underground mine, an external site at the processing area of the extracted material. For each of them the risks will be analyzed and the procedures for their containment defined. The exercises are carried out by the students in groups and are assisted by the teachers. For each of them a summary report of the activity carried out is drawn up; it is then presented and discussed during the oral examination.

Modalità di esame: Prova orale obbligatoria;
Exam: Compulsory oral exam;
The exam is in the written form (duration 1.5 hours). The successive oral exam consists of the presentation and discussion of the reports related to exercises carried out by the groups during the course and the presentation of an in-depth report on a specific theme of the program, also carried out in groups. The vote will be defined considering the result of the written exam (weight 65%), the evaluation of the exercises reports and their presentation and discussion (weight 25%) and the evaluation of the in-depth report and its presentation (weight 10%).
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam;
The exam is oral and requires answering questions regarding the course topics, including possible problem-solving related to actual cases. Students are expected to correctly understand the aspects of designing a safe working environment in different civil and mining construction sites and possibly understand and manage the risks associated with these works, in agreement with the expected learning outcomes.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
