A, mining survey work in the mine infrastructure, the importance of
Mine Surveying is an important basic technology work is a mine development, production process, an important part of mine surveying work throughout the whole story of each project of mine in the mine infrastructure and production, plays a very important role in be summarized as the following: resource development to play a pioneering role to play to ensure the role of daily production, resource utilization and construction play a supervisory role, play a guiding role in security. Measurement results as the basis for construction of the mine data is the basis of production safety to guide decision-making is a long-term mine planning, production design are based, are mine to open up in strict accordance with the design, production guarantees. Measurement accuracy and reliability of the results of a direct impact on mine production and safety. Therefore, to ensure project quality, improve the management of mine surveying is very important.
Second, the characteristics of the work of Mine Surveying
1. Mine Surveying work is a gatekeeper for design work, not because of the design is wrong and the wrong, so that coal mines suffer.
2. Mine Surveying is a hard work, which was mainly due to poor working environment, the instruments, tools, stupid, carrying inconvenience.
3. Mine Surveying is a particularly delicate work, "lose the least bit, hack away," is a measure of the true portrayal of the work.
4. Mine Surveying work is highly consistent, all the mines from Inoue to the pit, from near and far, measurement data is a whole system.
5. Mine is a measurement over a broad area of work, involving Ida within the ground the villages, rivers, railways, highways, bridges, sorghum and other underground structures and the roadway, face.
6. Mine Surveying is a back, with many participants, inside and outside the operational requirements at the same time, the collective work done.
7. Mine is a precision measurement by the people, equipment, measurement methods, and environmental factors affect the work.
Third, Mine Surveying cause of the accident
1. Mine survey work over a broad, difficult to manage, easy to create regulatory loopholes, triggering the accident.
2. There is no strict checking design drawings of the relevant information, using the wrong design drawings, to on-site construction survey causing the accident.
3. Staff by lazy thinking of the role of ideological or any other work not seriously careful, do not follow the regular operation of the measurement method of inspection, will cause an accident.
4. As the measurement data consistency, so the middle of a point on erroneous information, have resulted in all the data errors.
5. As the work of people involved in mine surveying, so if a person error, other staff and had not checked in time was found, then the resulting measurement of the outcome of the error.
4, in the mine surveying work, the implementation of total quality management
1. Full quality management. Measurements are a people involved to complete the work only if all participants have been done correctly in order to ensure accurate and reliable measurement results. Therefore, we should do the following four areas:
(1) make measurement of personnel and ideological work. Foster their spirit of hard-working and conscientious and meticulous, conscientious and meticulous rigor. Seminars on a regular basis, everyone knows about their own measurements accident, analyzed and discussed the reasons lie, what kind of damage caused and for the record as a warning to his own measurements, so that every surveyors firmly establish the "Quality First" ideas, to strengthen each person's quality consciousness.
(2) measurement techniques and skills training. Combination of work requires a planned way to learn the entire measurement expertise, exchange of experience, conditional, it can organize personnel to rotate out to learn measuring new technologies. And regular post training, and constantly improve the professional quality of all personnel, operational skills and problem solving skills.
(3) the establishment of surveyors job responsibility. To understand the post is responsibility, responsibility is extremely heavy; clear what to do themselves, according to what criteria do. From the director to head to the team members to develop personal responsibility, respectively.
(4) to carry out various forms of group activities, key measurements for each project, according to their level of accuracy required to develop a reasonable measurement programs.
(5) To give full play to the wisdom of all surveyors to identify the focus of section affect measurement accuracy and to develop measurement solutions.
2. Grasp the whole process of quality management. Measurements are a very strong continuity of work in front of the work done, a direct impact on the work that ensues, the entire process of quality management from the following controls:
(1) for each measurement, should be checking the reliability of the outcome of the last measurement, accuracy, limit of difference insisted that "coal measure of order," the relevant requirements.
(2) periodic inspection of nuclear equipment, tools, and never use the equipment in question, tools.
(3) carefully examine the design drawings are correct before they are allowed by the two pairs of operators ready to measurement data, the operating personnel to study measurement program, work underground test facilities.
(4) The measurement of all aspects of operations in strict accordance with the provisions of the standard measurement method measuring facilities, wells strict control on the information in a timely manner transfinite re-measured and tested additionally.
(5) Shi test process, each according to their personal responsibility, do their work.
(6) Shi test site, can not be messy because of site personnel, press, which leads to psychological stress, resulting in measurement or calculation error.
(7) Shi measurement process, should be recorded clearly, calculate accurately, the original records should be in this sketch.
(8) Shi measured after the on-site inspection records and the calculation time derivation is correct, check and correct before the wells.
(9) Shi consolidation test data archiving.
3. All-round quality management. The entire team as the management level, division of labor, which is responsible for the scope of the different sections, so the operating team should strengthen the organization and coordination to jointly do a good job survey work. Measurement of management at all levels to implement, from the director to the head, to each member of the vertical in the end. Will be on-site measurement of the quality assurance, extended to every measurement of the work and service work, horizontal to the edge.
4. Measurement analysis and management. In the survey, according to precision broad and flexible use of a wide variety of measurement method, calculation method, so that surveyors fast, high-precision measurements to do a good job for each one. In the measurement work is completed, according to measurement results, find the measurement accuracy, to guide future survey work. In the conditional premise, as far as possible the use of sophisticated measuring instruments and measurement methods. For the measurement of the incident, organizing the whole team, rigorous analysis, find out the reasons and for the record, while the whole group to discuss the same mistakes may occur in areas to attract everyone's attention and do a good job in the future work.
