The floor plan of the mining engineering is a comprehensive drawing reflecting the current status of mining engineering in the coal seam or mining in the mining layer.In the spatial relationship with neighboring coal seams, carry out the design of the area, modify the geological drawings, arrange the production plan, and make many aspects such as "three quantities" calculation.Lets introduce it below!
What are the elements of the floor plan of the mining engineering
The floor plan of the mining engineering is a drawing of mining engineering and geological conditions in the mining of coal seams or in its layers.The picture must include the following content:
a. Jingtians technical boundary line, protecting the border between coal pillar and other technical boundary lines, and indicating the name and approval number;
b. The adjacent lanes related to the mining of the coal seam in this coal seam and the main lanes must be indicated in the main lane and the work surface of the work face at the end of the month.Note the rail surface or bottom plate height;
c. Returning to the pick -up area, coal loss area or canceling or reporting the loss area, the return area of ??the recovery area should draw the position of the working face at the end of the month, and the appropriate location of each working surface on the picture, note the average minimum thickness, coal seam inclination, mining method, mining year yearAnd draw a small pillar -shaped coal seam; the coal loss area should indicate the cause and coal amount of coal loss; the cancellation or loss area must indicate the approval number and the amount of coal;
d. The position of the permanent wire point and the level point;
e. Exploration and information that indicates the buried coal seams, such as drilling and exploration lines;
f. Important minimum safety data, such as fire areas, stagnant water areas, coal and gas prominent areas, etc., and indicate the time, degree and other related situations;
g. Important industrial buildings, residential areas, railways, etc.;
h. The mining mining engineering and geological data within 1 OOM outside the Jingtian border.
In order to quickly enter the mining of the mining engineering plane into the computer, the digging engineering graphics system must be established to automatically combine graphs in the form of flexible data.
Data structure characteristics of the digging engineering floor diagram
As a carrier of storage mine information, the mining chart should facilitate maintenance and minimize data redundancy, and at the same time meet the needs of different user layers.The elements on the mining diagram can be summarized as four types of entities: points, lines, faces, and body. Any entity has a certain space and attributes.The space position is used to describe the distribution of the entity. The attribute data describes the characteristics of the entity. The two are inseparable and interdependent. The space position is the key. The attribute is attached to the space position.EssenceAny complex object is an orderly collection of these four entities or some entities.
The spatial position of the point -like entity is represented by ((x} y), and the position of the line -like entity is represented by an arithmetic set of a column, that is, [(x, y) (x, y)Y)], the surface of the surface is represented by a closed curve or a polygon, which is [(x, y) (x, y).The three -dimensional entity is represented by the closed surface and the inner point.
The entity attribute of the mining diagram has the attribute value, such as the point -like entity can be divided into physical points, annotation points, inner points, nodes, and corners.The properties include area, perimeter, neighborhood and overlapping. The characteristics of three -dimensional entities include volume, circumference and island.
The disadvantage of the plane map of the mining engineering
In recent years, many Chinese coal mine companies have entered the mining stage of old mines. The underground conditions are complicated, the mining layers are too large, and the mining engineering management of most coal mine companies still use the floor plan of the mining engineering as the main management tool.Management of mining engineering design, planning, planning, modification, and supplementary drawings in the graphic plan of the mining engineering.The management method of managing management on the map board has gradually been eliminated. The general management method is to help the interactive format of the human machine, that is, providing the floor plan electronic map of the mining engineering department through the geological measurement department, and the designer through the CAI) graphic platform.Complete the design and planning work on the floor plan of the mining engineering.But management is still a huge project.
At present, there are many shortcomings in the management method of mining engineering, and it is not better to reflect the dynamic characteristics of the mining engineering.Coal mine enterprise mining production system is a three -dimensional system that continues to change over time.To accurately achieve the decision -making management of mining production engineering, it is necessary to be able to grasp the changes in underground mining production projects in real time.The current management distribution is difficult to ensure the real time of information.
The expression of traditional geological information is to use floor charts (geological graphics, bottom plates and other high -line diagrams, strata/coal seams and other thick line charts, etc.) and sectional views (the geological cutting of the exploration line, drilling pillar diagram, etc.), as well as perspective and axis and axisSide diagram.The mining of coal mines is based on the results of geological measurement work.The traditional mining design work focuses on the plane map of the coal mine mining project. The mining design plan shall be reflected through the floor plan of the mining engineering.The work of mining equipment and mining safety technology can generally only appear very little content on the floor plan of the mining engineering, and most of the work cannot be reflected.The floor plan of the coal mine mining engineering is called "exchange chart", which is the core of command and management of coal mine production.
