摘要
针对山西阳城阳泰集团竹林山煤业有限公司高产高效回采工作面煤层瓦斯含量大、瓦斯涌量大的特点,在瓦斯抽放的基础上,1320综采工作面采用了双"U"型通风方式。通过对"U+L"型和双"U"型通风方式进行分析,得出了双"U"型通风方式的优缺点。指出,采用双"U"型通风方式有利于解决工作面瓦斯问题,为工作面安全生产提供有力保障。
Coal-seam gas content and gas emission on high yield and efficiency face in Zhulinshan Coal Co., Ltd. of Yangtai Group in Yangcheng in Shanxi is huge. The double ＂U＂ type ventilation mode was taken in the 1320 fully mechanized coal face based on gas drainage. Compared with ＂U ＋ L＂ and double ＂U＂ type ventilation, the advantages and disadvantages of double ＂U＂ ventilation mode were obtained, and it was pointed out that this mode can help solve the gas problems on face, and provide effective protection for safe production on working face.
