【摘要】：瓦斯是影響礦井安全生產(chǎn)重大災害之一。亭南煤礦是高瓦斯礦井,論文針對該礦高瓦斯煤層進行瓦斯治理,通過理論分析、數(shù)值模擬以及現(xiàn)場試驗,提出關于亭南煤礦204工作面瓦斯治理方案,實現(xiàn)礦井安全生產(chǎn)。 亭南煤礦主采煤層4#煤是高瓦斯厚煤層,204工作面是亭南礦首個大采高工作面,采高6m為高瓦斯易自燃超長綜采工作面。在首次回采開始的120天里,風巷出現(xiàn)高瓦斯?jié)舛忍鞌?shù)占總回采天數(shù)的46%,更為嚴重的是在開采初期瓦斯涌出量過大,有時瓦斯?jié)舛热掌骄翟?%以上多次出現(xiàn)上隅角瓦斯超限現(xiàn)象,給工作面的安全生產(chǎn)構成了嚴重威脅。 論文在國內(nèi)外對瓦斯運移規(guī)律以及瓦斯抽采工程研究的基礎上,依據(jù)煤礦開采學、煤礦瓦斯防治理論、礦山壓力與巖層控制學,通過數(shù)值模擬仿真分析瓦斯在煤層開采時的運移規(guī)律以及現(xiàn)場4#煤基礎參數(shù)測定試驗、瓦斯涌出量預測及瓦斯抽采半徑試驗確定了適用于亭南煤礦204工作面瓦斯治理方案,使得204工作面在開采過程中沒有發(fā)生瓦斯事故,保證了礦井的安全生產(chǎn)。
[Abstract]:Gas is one of the major disasters affecting mine safety production. Tingnan coal mine is a high gas mine. Through theoretical analysis, numerical simulation and field test, this paper puts forward a gas control scheme for 204 working face of Tingnan Coal Mine to realize safe production of coal mine through theoretical analysis, numerical simulation and field test. The coal seam in the main coal seam of Ting Nan Coal Mine is the first large mining face in the thick coal seam of high gas, and the mining height of 6 m is the super-long fully mechanized coal mining face with high gas spontaneous combustion. In the 120 days since the first mining, the days of high gas concentration in the wind roadway accounted for 46 of the total days of mining. What is more serious is the excessive amount of gas emission in the early stage of mining. Sometimes the gas concentration exceeds the limit in the upper corner several times when the daily average gas concentration is more than 1%, which poses a serious threat to the safety production of the working face. On the basis of the research on gas migration law and gas drainage engineering at home and abroad, the thesis is based on the theory of coal mine mining, coal mine gas prevention and control, mine pressure and strata control. Through the numerical simulation analysis of gas migration law in coal seam mining and the determination test of coal foundation parameters on the spot, the gas emission prediction and gas extraction radius test, the gas control scheme suitable for 204 working face of Tinan Coal Mine is determined. No gas accident occurred in the mining process of working face 204, which ensured the safety of mine production.
