摘要

Most outbursts of gas and coal occur along geological structural zones during mining. Recent research revealed that most outbursts occurred on the downthrow sides of faults, and the key reason is that the outburst coal,often known as tectonic coal or soft coal, mainly exists on the downthrow wall of faults-hanging of normal faults or footwall of reverse faults. This paper will mainly discuss the outburst prone on different sides of faults and its causes.
