1 First, explain the form, number, specialty, demonstration time and mine profile, and briefly introduce the mine production capacity, license, coal seam occurrence, geological structure profile, mine hydrogeological conditions, coal seam spontaneous combustion tendency, coal dust explosion, mine water inflow, development mode, ventilation mode, gender, mine water inflow, development mode, ventilation mode and recent mining area.
2. Secondly, the factors that are not suitable for mechanized mining are demonstrated by sub-item and sub-mining. The discussion should explain the data source of each factor, the actual exposure and verification of mining, analysis and prediction.
3. Finally, it includes the number of experts (no less than 5 in coal mine, geology, ventilation and electromechanical specialty), names, specialties and titles, and the signatures of the general manager and technical director (chief engineer).
