Calculation method of safe width of gasification cavity for medium-deep underground coal gasification

Calculation method of safe width of gasification cavity for medium-deep underground coal gasification

Underground coal gasification is currently the highest-temperature (over 1200 ℃) unconventional development method for fossil energy. Underground gasification of coal in the medium-deep (refer to the depth of 800～1500 m in this paper) has obvious advantages in improving the gasification pressure and...
