Embodiment 1

[0050] see figure 1 and figure 2 As shown, it is a schematic diagram of the first layout structure and a second layout structure diagram of the coal mining roadway provided by the present invention. In this embodiment, an auxiliary transportation roadway 1, a main transportation roadway 2, and a working face 3 for continuous mining are set.

[0051] When the roadway is excavated to point A on the extension end of the main transport roadway 2, retreat to point D to drive the joint roadway DC to increase or decrease the width of the working face, and then continue to complete the roadway excavation along the CG direction;

[0052] In the production process, when the coal mining face advances to point B, points A, B, and E are connected, and because the reloading and transportation equipment can no longer be shortened, it is necessary to withdraw the coal transportation equipment in BC section, so that the BC section cannot be shortened. The shortened reloading equipment is rel...

Embodiment 2

[0054] see image 3 and Figure 4 As shown, it is a schematic diagram of the third layout structure and a fourth layout structure diagram of the coal mining roadway provided by the present invention. In this embodiment, an auxiliary transportation roadway 1, a main transportation roadway 2, and a working face 3 for continuous mining are set.

[0055] When the roadway is excavated to point A on the extended end of the auxiliary transport roadway 1, retreat to point D to drive the joint roadway DC to increase or decrease the width of the working face, and then continue to complete the roadway excavation along the direction of CG;

[0056] In the production process, when the coal mining face advances to point C, after the three points A, C, and E are connected, the transportation and reloading equipment of the main transportation roadway 2 will not be affected, so it is only necessary to add ( Figure 4 ) or remove ( image 3 ) Hydraulic support and scraper chute. Increase the...

Abstract

The invention relates to a roadway layout method based on irregular mining areas. According to the shape of the mining area of ​​the medium-thick coal seam, the roadways are reasonably arranged. When the roadway is excavated, the third roadway and the joint roadway are excavated by setting the middle point of the roadway excavation. And the fourth roadway, thereby changing the length of the working face, so that the sum of the areas of the multiple rectangular mining areas within the mining area is the largest. The mining area design of the present invention can simplify the roadway system, effectively reduce coal loss, increase the coal recovery rate, make full use of coal resources, ensure and prolong the mining period of the coal mining face and the mining area, reduce the excavation rate, and have good safety conditions and improve the various economic indicators.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a method for arranging mining roadways in irregular mining areas based on coal field boundaries. Background technique [0002] When coal fields are divided into mine fields, natural conditions such as large faults, rivers, railways, and industrial sites are mainly used as the boundaries of mine fields. In this way, some irregular stages or mining areas will appear in the process of dividing the well field into stages or mining areas. Due to the influence of geological conditions, a large number of irregular and corner areas are difficult to recover. At present, the mining in irregular areas is mainly based on the room-and-pillar method, which has a low recovery rate, serious waste of resources, and many potential safety hazards. In order to control the destruction of resources and increase the recovery rate, the country has adopted compulsory resource integration measu...
