峰峰矿区的九龙口矿设计年产量120万吨,第一开采水平垂深717米,标高为—600米。现正处于基建阶段。该矿原定为超级瓦斯矿,主要开采的山西组2~#煤(俗称大煤)被认为是煤与瓦斯突出危险煤层。1974年经湖北煤矿设计院、峰峰矿务局及勘探部门推测第一水平2~#煤的瓦斯相对涌出量为51.2米~3/吨·日,1980年经抚顺煤研所测定参数,推测第一水平2~#煤瓦斯相对涌出最为37.4米~3/吨。同时,本矿与西部的泉头矿(开采-240米水平,超瓦斯矿)、
Fengfeng mining area of Kowloon mouth mine designed annual production of 1.2 million tons, the first mining level of 717 meters deep, elevation of -600 meters. Now in the infrastructure phase. The mine originally designated as super gas mine, the main mining Shanxi Group 2 ~ # coal (commonly known as large coal) is considered as coal and gas outburst dangerous seam. In 1974, Hubei Coal Mine Design Institute, Feng Mine and exploration department speculated that the first level of 2 ~ # coal relative gas emission was 51.2 m ~ 3 / t · day, in 1980 by the Fushun Coal Institute measured parameters, It is speculated that the relative emission of 2 ~ # coal in the first level is 37.4m ~ 3 / t. At the same time, the mine and the west of the head of mine (mining -240 meters level, super-gas mines)
