Article 1 In order to ensure the high standard and high quality of the roadway excavation construction, the operation procedures and operation essentials are met, the project meets the design requirements, the process flow meets the requirements of the formal cycle operation, the employees standardize the operation, and the safe and efficient construction of the roadway is specially formulated. This procedure. All personnel engaged in excavation work must carefully study and abide by the provisions of this regulation. Article 2 Anyone who participates in the construction of the roadway must carefully study the engineering construction organization design and operation procedures before construction, and be familiar with the application, construction conditions, construction methods, construction requirements, quality standards, safety measures and disaster avoidance routes of the construction roadway. As well as the performance and use of construction equipment, and must participate in the construction after passing the examination. Before the commencement of Article 3, safety inspection and safety confirmation shall be carried out, and the following inspections shall be carried out: 1. Whether all kinds of tools, equipment, machine tools, spare parts, etc. are required, and whether their varieties, materials, specifications, quantities, etc. meet the requirements. 2. Whether the roadway support in the working area is intact and whether the top support is safe. If you find unsafe problems such as damage, loss, etc., you should do so before you can do other work. 3. Is the ventilation of the working surface good? Distance from the face of the duct opening, gas and carbon dioxide concentrations, temperatures, etc. for compliance with safety rules and operating procedures of the coal mine, ventilation facilities are in good condition, normal. If it exceeds the regulations or is not normal, it shall not enter the working surface, report to the mine dispatching station, and take measures to deal with it. 4. Whether the temporary support and the empty top distance of the working surface meet the requirements of the operating regulations. If it is not in compliance or is not safe, it must be supported immediately. Otherwise, it is not allowed to enter the work surface. 5. Is the middle and waistline of the roadway correct? If there is a problem, the surveyor should be asked to make corrections in time. 6. Whether the electromechanical equipment and pipes, lines and tracks used are in good condition, and if they are faulty, they should be eliminated in time to achieve normal use. Article 4 During the construction process, the construction personnel must perform operations according to the construction organization design, operation procedures and the operating procedures to ensure the quality of the project and be responsible for the safety of the post. Article 5 When this work type is associated with the operation of other types of workers, it is necessary to contact and cooperate with each other before starting work to ensure safe construction. Article 6 Roof management must be temporarily supported and permanently supported in accordance with the construction organization design or operating procedures, and empty top operations are strictly prohibited. Article 7 During the construction, the system of knocking and helping the top is strictly implemented. Before starting work, before drilling, after shooting, before support, you should carry out the work of knocking and asking for help, and find out the dangerous rock in time. Article 8: The top-level work must comply with the following regulations: 1. The top job should be performed by two experienced personnel. One person looks for the top and one person observes the roof and retreats. The top person should stand in a safe place, and the observer should stand on the side of the person looking for the top person and ensure that the road is unblocked. 2, the top of the search should start from a well-maintained location, from the outside to the inside, first the top and the back of the two groups in turn, in the scope of the top is strictly prohibited from entering. 3, the top staff should wear gloves. When using a long tool to find the top, the coal shovel should be prevented from hitting the bottom. 4. When the top gang encounters a large piece of broken coal shovel, the temporary support should be set first to ensure safety, and then slowly find the crack along the crack and the bedding. Article 9 Construction workers shall properly protect the middle and waist lines and other facilities. It is strictly forbidden to change the middle and waist lines privately. Before drilling and supporting, it is necessary to review and extend the middle and waist lines, and strictly follow the line to ensure that the engineering specifications meet the design requirements. Article 10 Before driving through the old lanes, goafs, coal and gas outburst areas, geological structure change areas or passing nearby, the excavation roadway must be operated according to special measures such as preventing gas, water, fire and roof. If abnormal signs are found, the operation must be stopped, and the mine dispatching station must be reported. If the situation is critical, the warning sign must be issued promptly, and all personnel within the threatened area should immediately evacuate to a safe place; after the cause is identified and processed, the work can be entered. Working face to face. Article 11 The construction personnel who expose the coal seams or excavate in the outburst coal seams must learn and implement the special measures for prevention and prevention, and strictly operate according to their regulations. During the construction process, it is necessary to pay attention to the gas change and highlighting signs. When it is found that there are prominent danger signs, it must stop working immediately, evacuate to a safe place according to the disaster avoidance route, and report to the mine dispatching station quickly. Article 12 In the construction of through-passage, it is necessary to do a good job in accordance with the provisions of the measures for penetration, to strengthen and improve the support of the through-site to prevent roofing accidents. Article 13 When adopting the drilling and blasting construction method, it should adopt wet drilling, flushing rock gang, using water cannon mud, as well as comprehensive dustproof measures such as shooting spray, loading sprinkling water and purifying air flow. Article 14 In the process of excavation, civilized construction must be done well. All tools, materials, pipes, lines, etc. should be stacked, hanged neatly, the ditch is unblocked, there is no debris in the roadway, no silt, no water. Article 15 Construction of the roadway shall adhere to the roadway once, and the quality of the project shall comply with the provisions of the “Safety Quality Standardization Standards and Assessment Rating Measuresâ€. Strict quality acceptance system, each team, each process, each type of work should be self-inspection, mutual inspection, timely processing of unqualified projects, the project can continue construction after passing the project. Article 16 The excavation staff shall strive to learn and actively promote new technologies, new equipment, new materials and new processes, and continuously improve the level of technical operation.
