Beneficiation plant design and general layout of content: The total plan is a blueprint of the exact relationship between the concentrator plant location area is located.
Generally there are the following:
(1) Location map: The map should show the distribution of the original landform, topography, features, workers' villages and concentrating plants in the area; draw water supply, power supply, drainage, heating and steam supply, etc. pipeline layout situation; on the relationship between the original and the new railway, road, water and other routes and aerial tramway lines and caving range flood level, factory wall, etc., should be expressed clearly.
The drawing ratio is generally l/25000～l/50000. The figure should be marked with the legend, the north direction, the wind direction map, the coordinate network connected with the external transportation network and the coordinate numbers.
(2) General plan of the concentrator: The figure shall not only indicate the plane position of the concentrating plant and the buildings and structures related to the auxiliary facilities, but also indicate the vertical relationship between them.
The vertical arrangement mainly solves the problems of construction, structure, railway and road elevation; drainage method; type of step and slope reinforcement (retaining wall, slope protection, retaining wall); The location of the drilling of engineering geology should also be clearly stated. The proportion of the total plan drawing is generally l/1000~l/2000, and the proportion of the construction drawing design is l/500～1/1000. The map should be marked with a legend, north direction, wind direction, and a list of buildings and structures, and indicate the elevation of each factory floor.
(3) Integrated pipeline map: a modern mineral processing plant and various pipelines are intricate. According to the use, there are pulp, water, electricity, steam, fuel, communication pipelines, etc. According to the laying method, there are three types of above ground, underground and overhead. The diagram should clearly indicate the relationship between the pipelines, the way they are laid, and the form of some structures.
For complex pipelines and pipe racks, there should be a partial profile and indicate the relevant dimensions. The various pipeline symbols in the legend should be clearly stated. In the case of integrated pipeline configuration, the following principles and requirements should generally be observed:
1) When arranging pipelines, it is necessary to implement the principle of not occupying good land.
2) Minimize the impact on the expansion of the plant and material piles, and give due consideration to the transformation and expansion of the pipeline itself.
3) Comprehensively consider the nature, use, interrelationships and possible effects of various pipelines, and choose a reasonable direction and laying method.
4) When arranging underground, ground and overhead pipelines, it should take into account the safety of production, construction and maintenance, and meet the requirements of regulations and specifications.
5) When arranging pipelines, the engineering geological conditions should be taken into account, and the impact on the pipelines such as earthquakes, frozen soils and severely cold areas and expansive soils (fractured clay ) should be noted.
In the general graphic design, in addition to drawing the above-mentioned related drawings, it is necessary to propose: an explanatory table of buildings and structures; the area within the fence of the factory; the area of ​​buildings and structures (including belt corridors); the length of roads and railways; open storage warehouses and other venues. Area; construction coefficient; indicators of site and road earthwork volume.
