Study on fracturing monitoring and expansion law of underground gasification coal based on different gasification channel types

During the underground coal gasification process, the thermal stress produced at high temperatures will lead to coal cracking, which may cause gas leakage. Therefore, a real-time monitoring and regularity research of coal cracking is of significance for the long-term and stable operation of undergro...
