Contents of Working Regulations for Coal Mining Face-Labor Organization and Regular Cycle Operation
Labor organization and regular cycle operation.
1. Labor organization
Reasonable arrangements for the use of labor in collective labor and the improvement of labor (work) efficiency.
methods and measures. It mainly includes the determination of staffing, division of labor and staff allocation, labor cooperation.
The organizational form, working hours and shift system, etc.
2. Regular cycle operation
Within the specified cycle time, complete all procedures and work as specified in the operating procedures and cycle charts.
to achieve the expected progress.
(
1) Cycle mode. One cycle, two cycles, three cycles or multiple cycles within 24 hours.
(
2) Work form. Fully mechanized mining is generally "four or six operations", I .e. three shifts of production and one shift of maintenance. There are also
The use of "38 operations", that is, two production, one maintenance preparation;
Two shifts of coal mining, one shift of two mining and one quasi-operation, or three shifts of coal mining quasi-parallel operation.
(
3) Cycle progress. The mining face completes a cycle of forward advancing distance.
(
4) Organization of labor. The labor organization of coal mining face refers to the staffing of various types of work and its organizational form.
Labor organization and factors such as cycle schedule, cycle number, operation mode, working face length and roof and floor conditions
have a close relationship. At present, the labor organization of fully mechanized mining face is relatively simple, and it adopts the form of professional work combination.
Blasting
The working face labor organization mostly adopts the form of combining professional and comprehensive types of work. fully mechanized coal mining face shearer
The driver, moving support, pushing and sliding, conveyor driver, pump station driver, etc. shall be specially assigned to take charge; Blasting face
Blasting, mechanical and electrical maintenance, conveyor drivers, pump station drivers, etc. shall be in charge of special personnel, and other types of work shall be in accordance with the working face length.
degree, attendance, process arrangement, geological conditions and equipment conditions, etc., to determine the length of the segment, the branch,
Mining and returning tasks are assigned to teams and groups. The labor organization of general mining face can be divided into two categories: professional type of work and comprehensive type of work.
The specific organizational forms are chasing machine operations and segmented operations.
The chase operation is based on professional types of work, according to the production process, equipped with different professional types of work,
Follow closely behind the shearer along the working face, and move the frame, hang the beam, clean the floating coal and move the transportation in sequence.
Machine, pillar and other processes; segmented operation, is a combination of professional and comprehensive types of work, which is characterized by the addition of professional types of work.
In addition, the blasting working face divides the working face into several sections, each section is about 15~20m long, and each section is equipped with 2~3
Coal mining pillar worker is responsible for the work of hanging beam, cleaning floating coal, pillar, returning pillar and moving conveyor in this section;
In addition, there are also the first two forms of sub-group comprehensive operation, group relay chase machine operation and so on.
3. Cycle operation diagram
The cycle operation diagram takes the length of the working face as the ordinate, and generally one grid is 15m; The abscissa indicates the operation.
Class and time, each small represents one hour. Each process is represented by a different visual symbol (called a legend),
Draw into the figure.
Figure 3-1 is a cycle operation diagram of a fully mechanized mining face. The working face is l3Om long and "38 system"
The formal cycle of the industry. The first shift worked upward at the head of the working face from 2 o'clock to 4 o'clock to complete a knife of coal.
And complete the feed, in the process of cutting coal chasing machine, pulling frame and pushing slip; Cut coal from the tail of the machine at 4 o'clock and reach the head again at 7 o'clock.
Complete a knife of coal and feed it into the nose. Cut coal from the nose at 7 o'clock, stop the machine at 9 o'clock to the tail and feed the knife.
Maintenance will be completed at 10 o'clock when the shift is handed over. The second and third classes are the same as the first class.
