(1) Ensuring the safety of mining operations and good working conditions
Since mining production is carried out under complicated and difficult conditions, it is important to ensure the safety of workers' equipment, facilities and the entire mine. Ensuring a good working environment is an important principle for evaluating the quality of mining methods.
(2) Labor productivity requirements
Due to the complexity and heavyness of mine production, the current labor consumption per ton of ore is relatively large. Therefore, it is very important to adopt high-efficiency mining methods, adopt advanced technology and technology, continuously improve the mechanization level of mine production, and strengthen the scientific management of enterprises to improve labor productivity.
(3) Continuously increase the mining intensity
Increasing the mining intensity is conducive to completing and over-compensating the country's production tasks, reducing the maintenance costs and production management costs of the roadway. It is also one of the important measures to ensure the safety of work.
(4) Depletion requirements for ore loss
Loss of ore is a waste of national resources and increases the cost of ore. Two ore will increase transportation costs, improve costs, the real yield beneficiation and final product costs, enable enterprises to reduce production of the metal.
(5) Lowering the cost of mines
The main ways to reduce the cost of ore are to reduce labor consumption, increase the quality of ore produced, increase labor productivity, and reduce material and labor consumption.
Chest Muscle Training
The fitness equipment for chest exercises has diverse characteristics and can meet different training needs and goals.
1. Barbell bench press is one of the most common training exercises for chest muscles, mainly training the pectoralis major, shoulders, and triceps. When using a barbell push, it is important to maintain a straight back and stable shoulder blades, avoid excessive use of shoulder and arm strength, and adjust the weight and frequency of the barbell to suit your level of ability.
2. Dumbbell bench press is another common exercise for training chest muscles, which places more emphasis on the stability and balance of the chest muscles compared to barbell bench press. When using dumbbell push, it is necessary to maintain the stability of the arms and try to keep the movements of both arms consistent. A smaller weight can be used for dumbbell push to improve stability and grip.
3. A chest stretcher is a device specifically designed to train chest muscles, which can be adjusted to different body shapes and training needs by adjusting the position of the seat and handle. The advantage of chest thrusters is that they can more effectively isolate and stimulate the pectoralis major muscle while reducing the impact on other muscle groups.
4. A fitness ball is a multifunctional equipment that can be used for various training exercises, including chest training. By performing exercises such as bench presses and push ups on the fitness ball, the challenge and stability requirements for the chest muscles can be increased.
5. The pull-up device is used to exercise upper body muscles, including chest muscles. By performing pull ups, the development of chest muscles can be effectively stimulated. When using the pull-up device, it is important to maintain correct posture and movements, avoid shaking and excessive use of arm strength.
In addition, other equipment such as butterfly machines, fitness ropes, barbells, and flying birds can also be used for chest exercises. No matter which equipment is chosen, the key is to maintain correct movements and postures, grasp appropriate weight and frequency to avoid injury and achieve the best training results
