高瓦斯水掘工作面瓦斯涌出规律的研究
RULES OF GAS EMISSION FROM HIGHLY GASSYHYDRAULIC DEVELOPMENT FACE
【摘要】 通过对台吉矿11条水掘煤巷的现场跟踪测定,并用计算机处理和回归,掌握了台吉矿高瓦斯水掘工作面的瓦斯涌出规律,同时分析了水掘煤巷的瓦斯涌出与煤层赋存条件及掘进工艺参数之间的关系,解释了水掘工作面瓦斯超限严重的原因所在.并提出了针对瓦斯含量大的四煤层掘进速度应控制在8m/d以内的技术要求
【Abstract】 The rules of gas esmission from headings developed by hydraulic method in a highly gassy Taiji Mine,based on site measurement made in 11 headings and processing of data with regression method by computer. The relation between gas emission,seam occurrence and development parameters is studied. The reasons why the gas content in the heading face well in excess of the limit are described. It is proposed that the speed of drivage should be controlled within 8 m per day because of high concentration of gas in No.4 seam.
