Literature reviews
Petroleum refineries generate relatively large amounts of sludge waste from oil/water/solids separation, tank bottoms, waste water, and so on.
However, without volume reduction and appropriate treatment before disposal, refinery sludge will reduce the service-life of landfill sites and may result in an odor problem and create the risk of contamination, particularly on ground water, thus causing adverse health effects.

People enjoy daily interaction with the soil, water, wind, plants and animals.
In order to achieve this social dimension, people within the village shall grow food as much as possible within the community bio-region, support organic food production there, create home out of locally adapted materials, use village-based integrated renewable energy systems, protect biodiversity, foster ecological business principles, preserve clean soil, water and air through proper energy and waste management etc.
However, some unintended negative consequences from it are becoming more and more obvious and severe: air, water and soil pollution, huge amount of waste and trash, reduced cultural and biological diversity, wide-spread poverty, production of highly dangerous materials, the damage to the natural system’s ability of maintaining its healthy and fertile system.
The focus has been placed on how to reduce our waste release into air, water and soil, how to sand less materials to landfills while maintaining our living quality, how to improve the producing techniques so they deplete natural resources more slowly and produce fewer dangerous materials.
Acknowledgement The authors deeply appreciate the professional advices to this paper from Professor Ying Hua of Cornell University.

Lutrol F127 was slowly added to cold water (4°C).
The pH of formulations was measured (n=3) using a pH meter (Professional Meter PP-15 Sartorius, Goettingen, Germany).
A 5-mL aliquot of gel was transferred to test tubes (internal diameter about 1.8 cm) and immersed in a thermostat water bath at 4°C.
Block copolymer pluronic F127 gel was mentioned to be formed by H-bonding in the aqueous system, caused by the attraction of the pluronic ether oxygen atom to a proton of water [18].
The decrease in solubility of the PPO block of F127 in water would favor micellization and reduce the cmt.

Abstract: Low permeability, low abundance, water-bearing gas reservoirs are widely distributed in China, and their reserves constitute 85% of all kinds of reservoirs in current.
But with big output in the actual production, produce condensate oil and water bring high velocity flow effect, and it do a great impact on the gas flow rate.

In the first step samples
were solution treated at different temperatures, then water quenched followed by aging.
The Jominy samples were solution treated for half an hour on each temperature and then placed into the Jominy basin as quickly as possible and cooled by water.
Cu-samples to the experiments were provided by the Schmelzmetall Hungaria Ltd., Budapest and we thank them for the financial and professional support.

Based on the above excellent physical and chemical properties of composite materials,its application in coal mine is very broad, now on the application of composite materials in the coal mine are listed below:
The application of composite materials in the coal mine
The application of resin-based composite materials in coal mine
The application of FRP in coal mine
(1) Glass fiber reinforced plastic pipeline laying in underground mines
On the wet coal mine, piping erosion by acidic and water floats, easy to corrosion and scaling, this is the main causes of premature failure of metal pipe.
In the 1970 s, the FRP pipe have used in coal mine and underground for transport coal, water, wind, etc successfully in the United States, west Germany, Japan and other countries.
Reinforcing layer after curing, carbon fiber composite materials can replace pipe material to support pipe pressure because of Carbon fiber composite materials and healant all have high interlaminar shear, excellent corrosion resistance, excellent anti aging performance, low water absorption and good heat resistance performance, thermal expansion coefficient is close to the steel.
Conveyor belt in the belt transmission machine is made by composite materials which is composed of rubber and cord fabric . 2) Water delivery hose and pressure air hose which are used in a coal mine surface and underground are made of composite materials consisted of rubber and fiber cloth. 3) The tape hairdryer used in coal mine and metallurgy mine underground ventilation is commonly used rubber matrix composites product,so is the mineral tape hairdryer used in tunnel engineering and the mining of inclined or vertical shaft ventilation . 4) Coal mine hoisting rope made of composite material not only has the advantages of high strength, abrasion resistance, corrosion resistance, Light weight, soft and so on, but also plays an important role on enhancing the lifting efficiency.
