| 摘 要： | 基于石门揭煤过程中采掘应力场与瓦斯突出关系研究的需要,针对目前石门揭煤突出模型还处在实验室研究的阶段,而大部分都未能综合考虑瓦斯压力、地应力、煤的物理力学性质等对突出的影响,研制出一套能够综合考虑地应力、瓦斯压力及煤体结构的石门揭煤突出模拟试验系统。为取得准确、客观的试验效果,进行了密封、快速开启装置及氮气平衡系统等关键技术的设计,介绍了试验系统的主要组成结构、功能。利用该实验台进行石门揭煤突出试验,试验结果反映出在突出过程中地应力和瓦斯压力的变化情况,可为研究和揭示煤与瓦斯突出机制、突出过程中地应力和瓦斯压力的变化规律提供新的技术手段。

| Abstract: | Based on the research needs of the relation between mining stress fields and gas outburst during the process of rock cross-cut coal uncovering, a set of outburst simulation experiment system of rock cross-cut coal uncovering is developed which takes ground stress, gas pressure and coal structure into account comprehensively, while outburst model of rock cross-cut coal uncovering is still on the stage of laboratory research and most don’t comprehensively consider the effect of gas, ground stress and physico-mechanical properties on outburst. To get accurate, objective the experimental effect, the design of key technologies such as main composition structure, function of this experiment system, outburst roadway, quick opening device and nitrogen balance system are introduced. The experiment results reflected the change of stress and gas pressure during outburst in uncovering coal seam using this experiment system. This experiment system provides new technical means for studying on and revealling the change law of mechanism of coal and gas outbursts and ground stress, gas pressure during the process of outburst. |
