New lesson
1. What is a mine map? What role does it play in coal production?
A: The mine map is the abbreviation of engineering geological, measurement and mining engineering drawings, and is an important technical data for coal mine production and construction. In mining projects, various mine maps are often required to indicate geological conditions, to calibrate the location of the upper and lower engineering, and to indicate the progress of the mining project. Through the mine map, you can systematically understand the natural conditions of the well and plan the mining work.
2. What is a stereo picture?
A: A graphic that can simultaneously express the shape, shape and characteristics of the object in terms of length, width and height is called a stereogram.
3. What is the three views of the object? What are the three-sided projections of the three views?
A: The graph drawn according to the orthographic projection of the object is called a view. The object has the shape and size of three aspects: length, width and height. For example, if you make its Zheng projection from three aspects of the object, you can get three aspects of the object. A view of the true shape and size. By combining the three views, you can get the full shape and size of the object. These three views are the three views of the object.
Use three mutually perpendicular planes as the projection surface, which is called the front side of our face, the lower side is called the horizontal plane, and the other side is called the side.
4. What is the legend and scale?
A: The symbol used to draw the mine map is called a legend. When drawing a mine map, the shape and size of the actual object are very large. In order to facilitate the drawing, the drawing cannot be the same size as the size of the object, and then the ground object is reduced according to a certain multiple, and then drawn onto the drawing. The size of the object is called a scale compared to the actual size of the object.
5. What is the plan of the mining project?
A comprehensive horizontal projection map reflecting mining engineering, geology and measurement information is called a mining project plan.
6. What is the elevation and contour?
A: In order to indicate the height of a mine location, a comparison standard must be determined. This standard is based on the selected level of the sea level average water level as the standard for calculating the level. The vertical distance from a point in the mine to this level is called the elevation of that point.
In the coal seam, the points of the same elevation are connected into a line called the coal seam contour.
7. What is rock? How many categories?
A: The material that makes up the outer hard shell of the earth is called rock. It is made up of a mineral or several minerals. Rocks are divided into three major categories: slurry rock, sedimentary rock and metamorphic rock.
8. What are the characteristics of sedimentary rocks?
A: Most of the coal resources are buried in sedimentary rocks. The main features of sedimentary rocks are the presence of bedding and fossils.
9. How is the coal seam classified according to the inclination angle?
A: The inclination of the coal seam is at zero. -90. The change between +, it has a great impact on mining work, coal seams with different dips need different methods to mine. Therefore, the dip angle of the coal seam is used as a standard for coal seam classification. Coal seams are divided into four categories according to the size of the dip.
Near horizontal level. The dip angle is 8. The following coal seams, or open-pit mining, have an inclination of 5. The following coal seams.
, gently inclined layer. The angle of inclination during underground mining is 8. -25. The coal seam, also known as the gently inclined coal seam.
Medium oblique coal seam. The angle of dip is 25. -45. The coal seam, or open pit mining, has an inclination of 10. -45. Coal seam.
, steep coal seams. The angle of inclination is 45 in underground or open pit mining. Above the coal seam.
10. What kind of top plate can the direct top be divided into?
Answer: The direct top category of coal mining face is divided according to its stability during the mining process. It is divided into: one type of unstable roof; two types of medium stable roof; three types of stable roof; four types of very stable roof.

Sp; 6, safety quality standardized coal mine is divided into several grades, how are the assessment criteria for each grade?
Level 1: The average score of safety and quality standardization is 90 points and above, and the ventilation major reaches the first level. Among the five majors of coal mining, tunneling, electromechanical, transportation, and geodetic water control, no less than three majors can be reached. Less than two.
Level 2: The average score of safety and quality standardization is more than 80 points, and the ventilation professional reaches the second level. Among the five majors of coal mining, excavation, electromechanical, transportation, and geodetic water control, the number of secondary professional is not less than three. The major is no less than three.
Level 3: The average score of safety and quality standardization is more than 70 points, and there are no majors in coal mining, tunneling, electromechanical, transportation, ventilation, and geodetic water control.
7. How is the safety and quality standardization of coal mines' professional scores and coefficients?
Answer: 1), coal mining: 15 points coefficient is 0.15.
2), excavation: 15 points coefficient is 0.15.
3), electromechanical: 15 points coefficient is 0.15.
4), transportation: 15 points coefficient is 0.15.
5) Ventilation: The 30-point coefficient is 0.30.
6), ground test water: 10 points coefficient is 0.10.
8. What are the conditions that must be met for an approved safety and quality standardized coal mine?
A: Approved safety and quality standardized coal mines must meet the following conditions:
1), to achieve safety objectives: mine million tons of mortality: level 1: below; level two: 1.3 or less; third level: 1.5 or less.
For coal mines with an annual output of less than 1 million tons, it shall be assessed as a Class I mine. The annual death toll shall not exceed one person, and the death rate may be calculated cumulatively for three consecutive years. Coal mines with a death accident of 3 or more in the year will be disqualified from the current year.
2) The mining relationship is normal. 3) Resource utilization: The recovery rate meets the specified requirements.
4) The mine must have sufficient air volume approved; safety monitoring, gas drainage and fire prevention systems must be established in accordance with the provisions of the Coal Mine Safety Regulations.
5) Develop and implement a number of rewards and punishments system for safety quality standardization inspection.
