摘要
西北地区侏罗纪煤可采储量巨大,煤层自燃倾向性大,而侏罗纪煤层自燃机理研究落后于东部和华北的石炭二叠纪,因此了解西北地区侏罗纪煤层自燃研究现状对确立今后西北侏罗纪煤层自燃研究方向和完善煤层自燃理论体系具有重要意义。本文查阅参考了大量文献,总结了西北地区侏罗纪煤岩特征,详细阐述了侏罗纪煤的低温氧化自燃特性,并将现有的煤层自然发火模型推广应用到侏罗纪煤层,最终提出了侏罗纪煤实验室研究、数值模拟和现场实践的合理化建议。
The Jurassic coal of NW China has huge recoverable reserves but large spontaneous combustion tendency. The mine fire prevention work of Jurassic coal falls behind Carboniferous- Permian coal mine in the east and north China. Therefore,understanding the status of fire prevention of Jurassic seam of Northwest Region is of great significance to establish research orientation of spontaneous combustion of Northwest Jurassic mines and develop the theoretical system of spontaneous combustion. The paper summarizes Jurassic coal rock features of NW China,describes in detail its low temperature oxidation characteristics of spontaneous combustion and promotes the existing spontaneous combustion model to the Jurassic coal seams. In the end,further researchon laboratory studies,numerical simulation and field practice of the Jurassic coal is recommended.
