摘要
为了解决高瓦斯厚煤层综放开采合理工作面长度的确定问题,采用理论分析和现场实验的方法,在对高瓦斯厚煤层综放工作面长度的多种因素分析的基础上,对以工作面通风能力校核工作面长度的经验公式进行了比较分析,提出了适合综放开采的以工作面通风能力确定工作面长度的校核公式。并结合鹤壁四矿瓦斯赋存及涌出特点,计算得出了适合鹤壁四矿满足通风能力要求的合理工作面长度。该成果对高瓦斯厚煤层安全高效开采具有一定的参考价值和指导意义。
in the process of determining the length of mining face which influences the effect of mining, many factors influence the determination of the length for fully mechanized top-coal caving face. Based on the analysis of experiential expression to determine the length of face with ventilation capacity, one expression to determine the length of fully mechanized top-coal caving face with ventilation capacity is presented. Combining the feature of gas existing and emission from the fourth mine of Hebi Coal Mining Group, the rational length for fully mechanized top-coal caving face is determined.
