摘要

目的。改进煤尘爆炸定位装置的设计,提高其速度,通过可靠地压制火锋,提前与灭火剂云形成有效的屏障,从而阻止爆炸在矿井上的蔓延,增加人员对负面爆炸因素的保护。方法。采用了一种综合方法,其中包括对乌克兰矿井中甲烷-空气和粉尘-空气混合物爆炸的统计数据进行分析和归纳,对煤尘爆炸局部化方法进行批判性分析,对爆炸期间岩石变形进行计算机模拟。结果。所获得的爆炸能量在山体中重新分布的数据,科学地证实了一种获取激波锋面进路信息的定性新方法。研究结果证实,在地震波的影响下,在爆炸锋面前方沿生产方向移动的粉尘堆积的松动,为火灾锋面前方爆炸粉尘浓度的形成创造了条件。但是,地震传感器对爆炸存在的早期信号有助于形成防火前沿的防爆环境,并在火灾前沿的路径上提供可燃环境的预防和不可燃区域的创建。科学的新奇。提出了一种全新的煤矿爆炸探测方法,并在揭示山区环境中爆炸能量传播机理的基础上,设计了一种新的煤尘爆炸定位装置。现实意义。使用所提出的煤尘爆炸定位装置,可以加速粉尘爆炸的定位,通过可靠地抑制火锋,与灭火剂云形成有效的屏障,从而在采矿中创造一个防爆环境。

IMPROVEMENT OF MEANS OF LOCALIZATION OF COAL DUST EXPLOSIONS
Purpose. Improving the design of coal dust explosion localization devices to increase their speed, premature creation of an effective barrier from the cloud of extinguishing agent by reliable suppression of the fire front and, as a consequence, stop the spread of explosion on the mine, which will increase personnel protection from negative explosion factors. Methods. A comprehensive approach was used, which includes analysis and generalization of statistical data on explosions of methane-air and dust-air mixtures in mines of Ukraine, critical analysis of means for localization of coal dust explosions, computer modeling of rock deformations during the explosion. Results. The obtained data on the redistribution of explosion energy in the mountain massif allowed to scientifically substantiate a qualitatively new approach to obtaining information about the approach of the shock front. The results of the study confirmed that the loosening of dust accumulations under the influence of seismic waves, which are significantly ahead of the explosion front moving along the production, creates conditions for the formation of explosive dust concentration in front of the fire front. But early signaling from the seismic sensor of the presence of an explosion contributes to the formation of an explosion-proof environment to the approach of the fire front and provides prevention of the combustible environment and the creation of a non-combustible zone in the path of the fire front. Scientific novelty. A fundamentally new approach to explosion detection in mining is substantiated and a new design of a device for localization of coal dust explosions based on the disclosure of the mechanism of explosion energy propagation in the mountain environment is proposed. Practical significance. The use of the proposed device for localization of coal dust explosions allows to accelerate the localization of dust explosions, to create an effective barrier from the cloud of extinguishing agent by reliably suppressing the fire front and as a result to create an explosion-proof environment in mining.
