(a) the concept of stages and nuggets (1) Stage--The stage is to divide the main transportation lanes consistent with the strike at regular vertical distances in the mine field when mining the gently inclined, inclined and steeply inclined deposits, and divide the well field into the ore section in the vertical direction. Call this mine section a stage. (2) Stage height - Stage height refers to the vertical distance between the upper and lower transport lanes. Stage height variation range - The stage height varies widely. For gently inclined ore bodies, the stage height is usually less than 20-30 meters; The steeply inclined ore body, the height of the stage is usually 50-60 meters, and the individual has reached 80-120 meters. However, for different mining methods, the required stage heights are different. (3) Main factors affecting the height of the stage The stage height depends mainly on the conditions under which the impact occurs, and the mining method. As long as the conditions permit, the appropriate increase in the height of the stage can reduce the number of stages, reduce the amount of development, mining, and reduce ore loss and depletion. (4) Nuggets In the phase along the strike, the tunnel is connected to the next two adjacent stages of transporting the alleys, and the stage is subdivided into independent mining units. We call such mining units a nugget. The mining conditions vary depending on the conditions of the deposit. (2) Concept of panel and mining area (1) Panel 1 When mining level and micro-sloping deposits (ie deposits with ore inclination <5°), if the thickness of the deposit does not exceed the allowable (if the thickness of an ore body is more than 80 meters, if it is mined by shallow water mining method, then 80 meters exceeds The stage commonly used in the mining method is 50 meters high and should be mined in several stages. For example, it can be divided into 30 meters. According to the specific mining method, the stage height is no longer in the mine field. Divided into stages. In order to facilitate the work, the mine tunnel is divided into rectangular sections. We call this section a section. (When the thickness of the ore body is large, it is still divided into stages mining, such as iron ore Meishan). 2 Scope of the panel – the panel is the length of the panel at the boundary of the minefield. The distance between the lanes of the two adjacent panels is the width of the panel. 1 - main well; 2 - pay well; 3 - main transport lane; 4 - panel transportation lane; 5 - mining roadway; 6 - mining area; (2) Mining area 1) In the middle of the panel, at a certain distance, the mining and mining roadway connects the adjacent two lanes of transportation lanes, and the panel is subdivided into independent mining units, and this independent mining unit is called the mining area. 2) The area of ​​the mining area - the upper and lower sides are bounded by the stage roadway, the height is the stage height, and the length is bounded by the patio (or uphill) of the mining area. The length can vary from 10 – 40 to 30 – 60 meters depending on the mining method. 3) There are two situations when mining a gently inclined deposit. 1 When the thickness of the ore body is not large, the mining area can be arranged along the strike; 2 When the thickness of the ore body is large, the mining area can be arranged along the upper direction;
