平煤一矿丁6煤层突出危险性预测指标临界值实验研究

Experimental Research on Critical Value of Outburst Danger Prediction Index for Ding6 Coal Seam in No. 1 Coal Mine of Pingdingshan Tian′an Coal Company

  • 摘要: 为了考察平煤一矿丁6煤层硬煤、软煤不同的突出危险性预测指标临界值,使之更具有针对性和有效性,遂运用实验室瓦斯吸附解吸实验和理论分析相结合的研究方法,对实验数据进行统计分析并回归得出了瓦斯含量W和瓦斯压力p、瓦斯解吸指标V1和瓦斯解吸指标Q3、瓦斯解吸指标V1和瓦斯压力p之间的关系,最终基于瓦斯膨胀能确定了丁6煤层硬、软煤突出危险性预测指标瓦斯含量W和瓦斯解吸指标Q3的临界值,其中硬煤、软煤区域突出危险性预测指标瓦斯含量W的临界值分别为5.55、4.93 m3/t;硬煤、软煤工作面突出危险性预测指标Q3的临界值分别为0.20、0.26 mL/g。
    Abstract: In order to inspect the different critical value of the outburst danger prediction index between hard coal and soft coal in the Ding6 coal seam for No.1 Coal Mine of Pingdingshan Mining Group, it made the prediction more targeted and effective. It used the research methods with the combination of the experiment of gas adsorption and desorption in the laboratory and theoretical analysis to conduct statistical analysis for experimental data, it carried out regression analysis and obtained the relationship of gas content W and gas pressure p, gas desorption index V1 and Q3, gas desorption index V1 and gas pressure p, finally determined the critical values of gas content W and gas desorption index Q3 of hard and soft coal outburst danger prediction index in the D6 coal seam based on gas expansion energy. The critical values W of outburst danger prediction indexes of hard and soft coal were 5.55、4.93 m3/t. The critical values Q3 of outburst danger prediction indexes of hard and soft coal were 0.20、0.26 mL/g.
