Abstract:
The scope and development state of Combust ion Space Area( CSA) is an important factor, affect ing cont inuously stable proceeding for it s yielding g as process in the test of underground coal g asification. As an at tempt, we use the pulse Transient Elect riomagnetic Method ( TEM) to detect the CSA of underground coal gasification at Liuzhuang coal mine, T angshan. The geophysical characterist ic of the gasif icat ion coal seam is recounted briefly. The rat ionale of the TEM and detect ion method of the CSA in the underground g asificat ion stove for 9# and 12 # coal seam at Liuzhuang coal mine are int roduced, and then w e have an evaluation to test data quality of the part survey point. T hrough analysis and explanation of probing result s, the position and limits of the CSA in the underground gasif icat ion stove of the 9 # and 12# coal seam are basically found out , attaining the desired goal and ef fect. Thereby it has provided an essential scient ific foundat ion for us to formulate technology schemes of the underg round g asification.
