| 为增强我国煤矿的采煤效率,为沿空掘巷布置和采煤时的煤柱宽度提供可靠的数据支撑,本文以蒋家河煤矿综放开采式工作面为对象,采取理论分析、数值分析和实验室试验等方法,分析研究了工作面的顶板运移规律等,通过分析迎采动沿空掘巷围岩的稳定性,研究出更适合工作面的煤柱宽度,提出科学有效的方案,控制了迎采动沿空掘巷围岩的变形问题,解决了煤矿采掘的问题。根据各项实验结果显示,当迎采动沿空掘巷的煤柱宽度为6 m时,其围岩控制技术的应用会更加合理,并且围岩控制技术方案的结果数据对煤矿迎采动沿空掘巷有着重要意义。 |

| The purpose is to increase the mining efficiency of China’s coal mines and provide reliable data support for the layout of gob-side entrydriving and the width of coal pillars during mining. The caving face under combined mining technology in Jiangjiahe coal mine is taken as the object. The roof movement law of the coal caving face is analyzed and studied by theoretical analysis, numerical analysis and laboratory experiments. By analyzing the stability of surrounding rock of gob-side entrydriving in heading adjacent advancing coal face, the width of coal pillar which is more suitable for working face is studied, the scientific and effective scheme is put forward, the deformation of surrounding rock of gob-side entrydriving in heading adjacent advancing coal face is controlled, and the problem of coal mining is solved. The experimental results suggest that the application of surrounding rock control technology will be more reasonable when the coal pillar width of gob-side entrydriving in heading adjacent advancing coal face is 6 m, and the result data of the scheme of surrounding rock control technology is of great significance to gob-side entrydriving. |
