摘要

目的。对形成矸石堆场的煤矿矸石灭火设备的参数选择、工艺装置运行设备主要部件的选择以及煤矿矸石灭火设备的原理图进行了研究。方法。分析现有的防止废物堆燃烧的技术解决办法;对防止废物堆燃烧的技术解决办法的备选方案进行环境评估;为煤矿废弃物的利用创造了一种环保的设计技术。结果。在深入分析设备运行工艺单元主要部件的基础上,提出了喷淋系统公司生产的MFP型FullJet喷灌喷头。-美国,他们的主要优势被考虑在内。使用水力管网的便利性得到了证实,其中包括由“Aquatherm”-德国生产的聚丙烯材料制成的管道;管道的主要组成部分是“熔体”材料,文中介绍了其优点。泵送设备是一个组成部分,包括离心泵供水(1VNS 60-66)和(VNSp 2.5)供石灰石悬浮液到输送排土场的灌溉喷嘴。科学的新奇。提出了一种煤矿矸石(堆石)抗自燃灭火设备,该设备通过对矸石输送面进行单位喷淋的连续控制和管理,以一种惰性物质(石灰悬浮液)进行分散,防止矸石运行过程中形成活性燃烧中心,从而实现了新的结构元件的引入及其相互连接。及时用惰性物质覆盖排土场,减少了岩石与环境接触的时间,这是岩石排土场形成的重要阶段,特别是锥形的岩石排土场,无论环境条件的影响如何,都可以降低由于耐火排土场形成的运行和维护成本。实际的含义。废煤设备,灭火效率的使用可以获得由于连续工作通过覆盖转储质量与惰性混合运输,这降低了岩石与环境的联系,这是一个重要的阶段形成的岩石转储尤其是圆锥形状,并降低运营成本和维护由于耐火尾矿库不管的形成环境条件的影响。

JUSTIFICATION OF PARAMETERS FOR SELECTING EQUIPMENT FOR EXTINGUISHING WASTE COAL
Purpose. Investigation of the choice of parameters of equipment for extinguishing coal mining wastes that go to the formation of waste dumps, the choice of the main components of equipment for the operation of technological units and a schematic diagram of equipment for extinguishing coal mining wastes are proposed. Methods. Analysis of existing approaches to technological solutions to prevent combustion of waste dumps; environmental assessment of alternative options for technological solutions to prevent combustion of waste dumps; creation of an environmentally friendly design technology for the use of coal mining waste. Results. Based on in-depth analysis of the main components of technological units for the operation of the equipment, MFP FullJet irrigation nozzles by Spraying Systems Co. were proposed. – USA, their main advantages are considered. The expediency of using a hydraulic network, which includes pipelines made of polypropylene material produced by “Aquatherm” – Germany, are substantiated; the main component of the pipelines is the material “Fusiolen”, the advantages of which are given in the article. An integral part is pumping equipment, consisting of centrifugal pumps for water supply (1VNS 60-66) and (VNSp 2.5) for supplying limestone suspension to irrigation nozzles of the transporting dump mass. Scientific novelty. Equipment for extinguishing coal mining waste (rock dumps) resistant to spontaneous combustion is proposed, in which the introduction of new structural elements and their interconnection is achieved by the continuous control and management of spraying per unit of the transported surface of the dump rock, dispersed with an inert substance (lime suspension), which prevents the formation of active combustion centers during the operation of waste heaps. Timely coverage of the dump mass with an inert substance reduces the time of contact of the rock with the environment, which is an important stage in the formation of rock dumps, especially of a conical shape, reduces the cost of operation and maintenance due to the formation of fire-resistant dumps, regardless of the influence of environmental conditions. Practical implication. Efficiency from the use of equipment for extinguishing coal waste can be obtained due to the continuous work achieved by covering the dump mass with an inert mixture during transportation, this reduces the contact of the rock with the environment, which is an important stage in the formation of rock dumps of a particularly conical shape, and reduces operating costs and their maintenance due to the formation of fire-resistant waste dumps regardless of the influence of environmental conditions.
