In the old well construction plan 400 500000 cubic meters per day, formed the mouth capacity, and work hard for to urban areas by the end of gas supply
Old mining area development and utilization of CBM first period engineering is now in full swing. By the end of this year, plans to build the ground the coalbed methane well mouth, form smoke 400 nissan 500000 cubic meters of gas, strive for the gas supply to scale.
In order to ensure the production safety, xishan coal group company and shanxi coal group kirin's blue flame CBM company to cooperate, Syria to tuen mine, mine and east song malan ore mine, the implementation of the three high gas extraction and comprehensive utilization of CBM development project. This project commenced construction in October 2010, at present has set up a file in the old mining area in tuen mun aram, ore drilling 140 mouth, malan put gas in 9 mouth. The running situation of the look, every Wells in average daily volume is about 1500 cubic meters, has accumulated the gas production nearly 300000 cubic meters, showed the large-scale development in west hill mine the feasibility of coalbed methane.
According to relevant technical personnel introduces, in this year, is expected to complete a 400 mining area of coalbed methane (CBM), the mouth construction form nissan CBM 500000 cubic meters of gas production scale of taiyuan city, currently about half the highest demand for natural gas. At the same time, it will speed up related gathering transportation system, using the system and other auxiliary facilities for the construction of urban gas supply at the end of the year, to.
For this area of CBM reserves, according to introduce, according to early exploration, the above three prevention of CBM resources mine more than 200 cubic meters, the single well service fixed number of year, is expected to 10 years or so. In As the old mining area to see, here the coal resources, mainly in coking coal, such as more easily than anthracite, the generation of coalbed methane, and collect and mining. At present development and utilization of CBM in Shanxi Province than good review made by the development and utilization of the future, here more potential.
With the rapid development of the project, the near future, the ground extraction drilling in areas of the old picture will present in our eyes. In the future, the entire west hill mine, will total construction of coalbed methane (CBM) 2000, annual output of coalbed methane can realize mouth 1 billion cubic meters, the annual output 850 million cubic meters, most of the production in mining area since ancient times. This can not only supply the entire family of taiyuan district 1 million daily use of fuel gas, but also as a taxi, large truck fuel, etc, so as to reduce greenhouse gas emissions, "gasification of shanxi", and beautify the taiyuan will play a positive role.
In addition, the old coalbed methane will become the valuable clean energy controllable in taiyuan city, the gas prices in establishing the comparative advantage, bring down the price of foreign and the air has positive significance.

Coalbed methane gas, commonly known as the main component is methane), is CH4 (primarily in coal mine, the associated gas is a kind of high calorific value, pollution-free new energy. It different from any conventional oil and gas, is mainly sorption state adsorption on coal seam in the pore. At present the main way of coalbed methane (CBM) mining is buck by extracting, drainage of the unconsolidated confined aquifer, make pore water in the coal seam gas get more space, activity increases, pressure is reduced, when pressure to a certain degree, methane gas from the pore surface desorption out, by diffusion fissure system arrived after the seepage near wellbore to output.
