Coal Mine Production Safety: Practical Application of "Silo" Theory

Because the different levels of coal mine personnel have different knowledge of safety knowledge and different work experience, they have different understanding of the hidden dangers on the site, and there are differences in the investigation of hidden dangers, as well as initiative and passiveness. Some people go downhole inspections only highlight the major hidden dangers and make them more prominent. The problem is dealt with, and ignoring small hidden dangers or hidden dangers, long and unrelenting, leading to accidents. Reviewing the accidents that occurred in coal production, most of them were caused by minor accidents that led to major accidents, which brought immense pain to employees and families, caused economic losses to enterprises and countries, and adverse social impacts. Screen theory was used to investigate hidden dangers. Law is the most effective way to solve this problem.

Composition of 1 sieve

Screening hidden dangers in safety production is using a series of safety knowledge and blood of national security laws, regulations, “Coal Mine Safety Regulations”, “Safety Technical Operation Regulations”, Operational Procedures, Measures, Enterprise Safety Directives, Safety Regulations, Regulations, etc. Lessons and years of work experience precipitated and formed as a sieve with a strict vision. In the screening of on-site safety conditions, it is necessary to ensure the scientificness, effectiveness, and safety of the screen. Excessive screen size will lead to leakage of hidden dangers on the site, resulting in production with hidden dangers, leaving fuses for accidents and causing accidents at any time.

If the size of the screen is too dense, the size of the hidden dangers cannot be separated, and the impact of the production will be affected. Therefore, the screening goal must be calibrated with systematic safety knowledge and mature work experience, and all hidden dangers must be screened out to ensure a good safe production environment. The formation of safe production promotes mutual development and coordination.

Application of 2 sieves

In order to give full play to the role of the sieve, we must first strictly implement the safety responsibility system and accountability system for all levels of personnel. The management personnel shall be responsible for the implementation of the 24-hour responsibility system. The accidents at the scene shall be strictly investigated for those who have visited the field 24 hours later, in accordance with professional, regional, supervision and inspection, The four-person responsibility system is directly responsible for the investigation and the safety and security personnel are subject to cross-cutting vertical and parallel regional investigations. The responsibility is investigated and the punishment is reached. We must ensure that everything is responsible and that there is accountability for dereliction of duty and form a strong safety responsibility system and guarantee system.

From the manager of the mine to the employee of the post, the hidden dangers are screened according to the scope of responsibility, and the management personnel go into the walk-through management, and each time they go down from the system to the site to strictly screen. The employees focus on screening and screening of hidden dangers in the workplace. They must immediately stop the operation to correct the hidden dangers that threaten the safety production. Generally, the hidden dangers are raised and fixed. The hidden troubles that cannot be rectified at that time must be reported promptly to make a good record ; professionals should promptly formulate treatment measures. , The Information Office notified the D- card to notify the unit to implement the rectification of the responsible person within a time limit, and to implement the system for setting up the document to eliminate the number, and form a closed-loop management of the hidden troubles from screening to implementation of rectification, inspection and cancellation No. 5WIH .

While screening the hidden dangers at the site at any time, implement the regular five-level screening hidden dangers ( mines, specialties, district teams, teams, posts ) , regularly screening hidden dangers in this area according to site conditions, and screening hidden dangers. Timely formulation of treatment measures, implementation of corrective time, acceptance of people. At the same time, the implementation of the hidden danger reminder system will promptly notify everyone of the hidden dangers, and the units will be posted on the wall so that the employees will have a good idea and will always be on guard against hidden dangers and dealing with hidden dangers.

3 Continuously enriching sieve knowledge is the key to screening hidden hazards on site

In order to screen out all the hidden dangers of various types of work in various fields, it is impossible to achieve a good screen and a strict scientific screen. Therefore, we must constantly enrich the knowledge of screens.

(1) Strengthen staff training and learning, make full use of the combination of collective learning and personal studies, implement homework law, study cards, on-site questions, organize examinations, professional major classes, and case plus case training methods so that employees can pass three major procedures And knowledge systems such as safety systems and safety regulations are studied to continuously improve business knowledge and ability to discriminate against hazards. At the same time, it will strengthen the implementation of the base training plus classroom training for staff training. After training and learning are applied in the future, it will become a use of reverse training that must be learned to fully improve the learning effect. On the basis of theoretical learning in the classroom, we will focus on the simulation practice exercises in the test bases, master the operating techniques and hidden danger check points, and comprehensively improve the staff's formal operation level and the ability to troubleshoot the positions.

(2) Strengthen the mutual learning in sieve theory application. Do hidden risks from practice to practice. The implementation of on-site inspection of the retention system, management personnel to go down the inspection must be walking routes, identify problems, rectification issues, rectification time, name records on the site to keep the name book, and notify the site of the hidden dangers of safety supervision officers and team leader. Stay tuned. In this way, the on-site inspection responsibilities of the management personnel are strictly implemented, and more importantly, we promote the joint learning of hidden danger screening, the seven major professions of coal mine production, mining, excavation, machinery, transportation, communication, and groundwater control and safety management. There are different businesses and expertise, different professions are skilled in this professional business, relatively detailed and strict screening of on-site hidden dangers, and the screening of hidden dangers is recorded in the name book, which is a good opportunity for other people to learn, so that as time passes, various professions Learn from each other, learn from each other, continue to enrich the hidden dangers of screening knowledge, so that everyone becomes on-site safety management, hidden talent screening talents.

4 sieve screening method for implementation of hidden dangers

(1) Screening the level of hidden dangers. According to the degree of danger and priority of hidden dangers to safety production, the hidden danger level is classified and measures are formulated to deal with it in time ; (2) Sort out hidden danger categories. Which professional hidden dangers, prone to hidden dangers, under what conditions and conditions, hidden dangers, what time prone to hidden dangers, find out the hidden dangers, and develop appropriate measures for prevention and control ; (3) to ensure the site safety environment. The cadres and employees screened hidden dangers on the spot, timely detected the hidden troubles, and created stable production conditions for safe production.

Through the implementation of the Qiaogou mine in the search for coal residue, on-site faults, old empty, old lanes, complex geological conditions, increased production links, and various types of unsafe factors continue to emerge under conditions that overcome difficulties to create a safe production Up to now, more than four consecutive years of safe production have been achieved, and the on-site safety production level has been comprehensively improved.

5 conclusions

In the process of screening hidden hazards on the site, how to master the goal of screening is the key. The goal of the screen is not fixed, there is no fixed size, only according to the site conditions change, the quality of the staff's business and "coal safety regulations" and many years of experience Accumulated, how to properly rely on active exploration and conscientious summary.
