1. Ecomonic construction need
With the social progress and domestic economic development,louis vuitton men handbags, the demand for resources and energy from human is increasing, whereas, recourses in our country is not rich. The mining depth is becoming more and more tremendous with the exploitation of resources, besides it stretches towards the mainland. Resource exploitation deteriorates day by day and the situation of secure exploitation is becoming much more serious. The coal mining depth in our country has already got to 1000m, metal mining depth to 1380m. it becomes more difficult to exploit resource as influenced by the increase in the ore deposit mining depth, the factors of underground water, gas, high geostress, geological structure.
Automatic man less mining face will become the direction of underground or hazardous mining, and also an effective way to ensure a secure exploitation during the work. Integrating the mining science, automatic technology, communication technology, computer science and technology to implement the basic theory of automatic man less mining face and develop new technology, new equipments so as to enable the mining machinery( ore beneficiation ) to advance towards robolic and intelligent direction.
There plenty of strategic metal mining resource that makes a secure exploitation of the marine mining resource, supplies technical assistance to guarantee a country marine rights as well as the national economic development, ensures a sustainable development of the society. To achieve mining underground requires developing some digital mining facilities like ROV.
2. Harmonious development need in face of natural environment
The manufacturing is obliged to transform from the mode of purely pursuing scale and profit to the mode of building economy-oriented 4R.
Turning to the natural environment to realize harmonious development requires mining machinery being ecological by means of all kinds of senior techniques to update manufacturing mode, resource and crafting organization, hence, to eliminate or at least minimize the environmental contamination during the products lifespan, maximize utilization rate, minimize energy consumption. Eventually, it will realize the harmonization between economic benefit and social benefit of the enterprise. There are two types of women if categorized them according to usage of bags.
