Abstract

The objective of this paper is to substantiate the method of construction and design parameters of explosion-proof stoppings for the quick and safe remote sealing-off of the sources of complex fires and explosions in coal mines. A new method was designed for the remote erection of explosion-proof stoppings in mine workings and a mathematical model of mass transfer through the body of a stopping made of discrete material. Tactics were improved for the containment of underground fires and explosions due to rapid remote erection of explosion-proof stoppings. The technology of the quick erection of stoppings made of rocks crushed by an explosion for sealing-off of the emergency sections of the mine has been proposed. A computational model and a method for calculating the parameters of explosion-proof stoppings erected by the method of directed explosion have been created. The results of the calculations open the possibility to prepare the means of containment of dust explosions in advance and to improve the tactics of safe containment of explosions and fires.

确定了快速搭建防爆停机的参数

本文的目的是为煤矿复杂火源和爆炸源的快速、安全的远程封闭，确定防爆止爆装置的施工方法和设计参数。设计了一种煤矿井下隔爆装置远程架设的新方法，建立了隔爆装置体传质数学模型。由于快速远程安装防爆止爆装置，改进了地下火灾和爆炸的遏制策略。提出了用爆炸破碎岩块快速安装封堵矿井应急区段的技术。建立了定向爆炸法安装的隔爆装置的计算模型和参数计算方法。计算结果为提前准备粉尘爆炸的遏制手段和改进安全遏制爆炸和火灾的战术提供了可能性。
