系统综述了前人研究煤与瓦斯突出的物理试验方法及理论成果,得出突出物理模拟试验分为瓦斯压力破膜突出模拟试验、人工缓慢干扰突出模拟试验、点火爆炸气压突增模拟试验、瞬间卸压突出模拟试验、间接突出试验5种方案;渗流试验由单一影响因素向多影响因素综合分析,并得到各因素影响渗流变化量的规律。认为目前该类试验研究为静态-突出模拟而非动态-突出模拟;没有研究机械振动作用下含瓦斯煤体渗流特性;没有研究突出前后瓦斯渗流规律;未系统分析煤体力学性质、瓦斯解吸吸附、渗流、煤体变形特征与突出破坏特性间的关系,以及机械振动对煤体强度、瓦斯解吸吸附、渗流、突出的影响。
The physical experiment methods and theoretical results of previous studies on coal and gas outburst are systematically reviewed. It is concluded that the outstanding physical simulation tests are divided into gas pressure rupture membrane prominent simulation test, artificial slow disturbance prominent simulation test and ignition explosion gas pressure sudden increase simulation test. Pressure relief simulation test, indirect test five kinds of programs; seepage test from a single factor to a comprehensive analysis of multiple influencing factors, and the factors that affect the variation of seepage flow. It is considered that the current experimental study is static-salient simulation rather than dynamic-salient simulation. The seepage behavior of gas-bearing coal under no mechanical vibration has been studied. The laws of gas seepage before and after salvage are not studied. The mechanical properties of coal, gas desorption and adsorption , Seepage, the relationship between the deformation characteristics of coal and the prominent failure characteristics, as well as the mechanical vibration on the strength of coal, gas desorption and adsorption, seepage, highlighting.
