Factors in tunneling engineering

1. Quality training of construction personnel If a project is not attended by anyone, it will never be realized. Whether it is fully automatic mechanized operation or full manual construction, the construction personnel are the key factors, and they can play an active role in the construction process, which exceeds any other factors, including the following two points:
(1) The quality of laborers The quality of workers mainly includes education, technical proficiency, labor enthusiasm, and safety education. There are many factors affecting underground mine roadway excavation. For example, the operator does not follow the procedures, the operator's cultural level is relatively low, the production process is not familiar, the performance of the production equipment is not enough, and the operation is unskilled. Therefore, it is especially important to increase the skills training for workers before and during the construction process. The improvement of labor skills of workers can greatly improve work efficiency. Before the construction of the new process, technical training should be carried out for the employees so that the workers can master each process and requirements as soon as possible, so as to ensure the smooth progress of the construction process. In the excavation construction, the staffing is complete, the division of labor is clear, and the cooperation is closely coordinated. The projects are closely connected, the working hours are effectively utilized, the work efficiency is improved, the quality of the workers is improved, and as many versatile as possible are cultivated. The efficiency of tunneling remains at a high level.
(2) Manager's ability The technical level, organizational ability, management ability and training ability of managers, especially the grassroots direct managers, are particularly important in construction organizations. During the construction process, the operation procedures and technical delivery quality are poor, the guidance for production is not strong; the safety regulations are not perfect, the on-site management is not in place or the management system is not implemented seriously; the technical personnel have low professional quality, and the roadway tunneling design is unreasonable. The imperfect production process and the unreasonable design of the support will cause hidden dangers to the production, thus affecting the smooth progress of the construction.

2. Management organization form

(1) The basic management system is sound and the management system centered on the post responsibility system is the guarantee for the smooth implementation of construction technical measures, construction equipment and construction organization, speeding up construction, reducing production costs, and ensuring construction quality and The basis of security.

(2) Reasonable construction method For roadway excavation, adopt one-time excavation molding or multiple excavation molding methods, and carry out advanced support or initial support according to surrounding rock conditions, and strengthen support in necessary sections to ensure safety. In the process of support, the improvement of the application process, such as the use of wet spray process, the use of anchor support for the self-supporting ability of the surrounding rock, not only reduces the labor intensity of workers, but also improves the construction environment.

(3) Scientific construction organization Scientific construction organization requirements to make the following points: 1. Determine the operation time and cycle time of each process, and try to compress the time outside the key process on the key line; 2. Parallel operation of multiple processes; 3. Preparation Reasonable and efficient cycle chart, optimize labor organization; 4. Reasonably select construction operation mode and circulation mode; 5. Determine the cycle of reasonable cycle footage.
