| 摘 要： | 三汇二矿浅部K_1煤层在无解放层开采的条件下,对该区打了探孔23个,对10项瓦斯地质判别参数进行了测试,对有关瓦斯地质相关因素进行了分析研究,预测该区虽为突出威胁区,但因存在有利瓦斯排放的因素,故可不开采解放层,采取合理的防突措施进行开采。现已在该区内开巷5000余m,工作面推进2000多m,采出煤炭50万t,经济价值达两千多万元。是瓦斯突出预测报用于生产的典例。可在条件相似的矿井中推广使用。

| Abstract: | Mining a coalbed without gas release, we have drilled 23 holes in the shallow coalbeds of K1 in the No.2 mine field in Sanhui coal district, tested 10 decision parameters, studied the correlation factors of the gas geology, and predicted a gas burst zone for here. So, it is feasible to lake burst-proof measures in a producing coalbed without mining the gas release bed. The existing mine opening is 5,000m long, the heading face has moved forward for 2,000m. 500,000t coal has been mined, with a worth of 20,000,000 yuan. This is a successful example to utilize gas burst prediction for mining coal, which may be popularized m the mines with the same conditions. |
