Stope safety management system
First  Each stope must have two safety exits, and connect the upper and lower roadways. The sidewalks should be located outside the veins. The support of the safety exits must be fastened and the ladders must be provided. If there are two exits due to special circumstances, it must be Approved by the company security committee.
Second  The mining site has a reasonable mining sequence, and the mining site is basically smooth and unobstructed.
Article 3 Â The mining mine funnel should meet the requirements of the support regulations. The depth of the mine should not exceed 3.5 meters, and there is a qualified sieve.
Article 4 Â The stope operation must have sufficient lighting, and must be operated strictly in accordance with the safety operation rules of each type of work.
The pulverizer is a machine that crushes large solid raw materials to the required size.
According to the size of the crushed material or crushed material, the pulverizer can be divided into coarse pulverizer, pulverizer and ultra-fine pulverizer.
There are four kinds of external forces applied to the solid during the crushing process: shearing, impact, rolling and grinding. Shearing is mainly used in coarse crushing (crushing) and crushing operations, and is applicable to crushing or crushing operations of materials with toughness or fiber and bulk materials; Impact is mainly used in crushing operation, suitable for crushing brittle materials; Rolling is mainly used in high fineness grinding (ultra-fine grinding) operation, which is suitable for ultra-fine grinding of most materials; Grinding is mainly used for ultra-fine grinding or ultra-large grinding equipment, which is suitable for further grinding after grinding operation.
The actual crushing process often involves several external forces acting at the same time, but high-end pulverizers are tailored according to the crushing environment.
