为解决石门揭煤突出危险性预测指标现场检验的困难,在对相似理论进行研究的基础上,针对突出发生的力学条件,采用因次分析的方法,对实验室进行突出模拟试验与现场相似的条件进行了分析。据此设计了实验室的突出模拟试验装置。通过在该装置上施加与现场相近的地应力、瓦斯压力进行了突出模拟试验,并在相同条件下对各石门揭煤突出危险性预测指标进行了测定,研究了使用各指标进行预测的准确性。为石门及井筒揭煤突出危险性预测指标的实验室检验创造了条件。
In order to solve the problem of on-site inspection of the index of outburst danger in exposing the coal seam in Shek Mun, based on the researches on the similar theory, the method of factorial analysis was adopted to highlight the occurring mechanical conditions and the simulative experiment in the laboratory was similar to the site Conditions were analyzed. Based on this, a laboratory simulation test device is designed. Through the application of on-site stress and gas pressure on this device, the outburst simulation test was carried out. Under the same conditions, the prediction indexes of the outburst danger of exposing to rock in Shimen were determined. The accuracy of forecasting using each index was studied. . Which provided the conditions for the laboratory tests on the prediction indexes of the outburst danger of exposing coal in Shimen and wellbores.
