Supplementary Technology of Gas Drainage
，rapidly making adsorption and isothermal adsorption test, simulating original reserve conditions, and accurately determining the gas volume in the coal seam
，testing well technology, mainly determining the permeability ratio of coal seam
，reservoir pressure and epidermis coefficient etc
，reservoir simulation and surface horizontal drainage design
CDM Project Consultant and Service for Colliery and Coalbed Methane Company
，evaluating and confirming the project with potential of carbon emission reduction
，helping company to complete the preparation work of CDM application, registering, endorsing and approval.
，making application to China CDM management institute and legal body of UN, and obtaining the issue of ＾authenticated carbon emission reduction volume￣
，purchasing ＾authenticated carbon emission reduction volume￣, helping the customer company to realize CDM project value
，tracking the project to ensure the smooth implementation and completion of greenhouse gas emission reduction
Surface Drainage of Coal gas！！Dymaxion Drilling
，side directional/vertical well！widely applied before mining, the vertical well discharges the gas from water
，multi-directional/single coal seam/vertical well！V shape layout between two side horizontal wells and vertical well. The vertical well discharges the gas from water
，multi-directional/multi-coal seam/vertical well！used to multi-targeted coal seam, the vertical well discharges the gas from water
，single side directional/super deep well！the bending radius cant be realized in the shallow coal seam with small covering thickness. The vertical well discharges gas form water
Underground Gas Drainage Technology！The movable drilling rig is used to drain the gas when drilling boreholes in the working face of coal seam
CAMDA Technology Service
China Australia Mining Development Alliance owns the most advanced the geological directional and drilling technology and has completed 30 surface development wells. It first reduces the mine development cost and it is an agent of foreign advanced generator group to work out plan for the gas power generation and assist to develop CDM project.
