摘要
动力灾害危险性的评价及防治必须有针对性,根据多因素耦合法,划定不同危险程度的区域,再采取相应的措施。依据某矿井1301工作面的实际地质情况,分析了各种诱发灾害的耦合因素。对含有冲击倾向性煤层的危险性做了安全评价,得出了矿井静态危险区的分布。而且对"潜在危险区"采取煤体深孔卸压,解除工作面存在的安全隐患。为此类矿井冲击地压的预测防治提供一个良好的方法。
Dynamic hazard evaluation and prevention must be targeted, according to the multivariate coupling method, the degree of risk in different areas delineated, and then take the appropriate measures. Based on 1301 actual geological conditions of a mine face, analyzes various induced disasters coupling factor. Coal seam containing the impact of the risk propensity safety evaluation done, come to mine the distribution of static danger zone. And taking the coal deep relief on the 'potential danger zone' relieves face security risks. And for such mines provides a good way to rockburst prediction and prevention.
