Advatege Vs Disadvantage

Continues mining process technology

(连 续 开 采 工 艺 的 优 缺 点) Advantage(优点)

1．High degree of automation, high efficiency, strong mining, suitable for the production of large open-pit mine(自动化程度高、生产效率高、开采强度大，适合于生产规模大的露天矿)

2．Low equipment operation cost. (采运排设备运营费用较低,成本较低)

3. Electric take place of oil. Tracks can be cut. Not restriction by the oil source and the price.(以电代油，可不使用卡车，不受油源和油价的制约.)

Disadvantage(缺点)

1．High investment, because Wheel bucket mining system is a special manufactured equipment according to special condition in mines. There is no finalize the design equipment.

(投资高，原因主要是轮斗是根据矿山具体条件 制造的专用设备，没有定型设备。)

2．Low reliability. Assembly line work, As long as a link out of the question, the system needs to stop.

(流水线作业，只要一个环节出了问题，整套系统需停机，可靠性较低。)

3．Influenced by climate. When it below -25°C, it must be shut down.

(受气候影响较大，在冬季-25°C以下时，须停产.)

4. Longer Manufacture, installation and commissioning period.

(制造、安装、调试周期较长。)

5．Frequently moving equipment if arrange working face belt. It will affect production. (如布置工作面胶带，则移动设备较频繁，影响生产.)
