近年来,通过采矿部门、矿山技术监察机构和煤矿联合公司之间的密切合作,在预防冲击地压和瓦斯突出方面取得了很大的进步。据1977～1986年间的统计,年平均冲击地压数约为3次。总共有60名矿工在场,其中10名丧命。虽然随着开采深度的增加而危险性增大,但是由于采取了技术上的安全措施和组织管理工作,冲击地压的数量并未增加。 1977和1978年中,伊本比伦矿有突出危险的53号煤层发生了大量的煤与瓦斯突出。采用解放层开采后,煤与瓦斯突出数量大大减少。1977～1986年期间,在西德平均每年记录到7次煤与瓦斯突出。在这些煤与瓦斯
In recent years, great progress has been made in preventing rockburst and gas outbursts through the close cooperation between the mining sector, mine technology inspectorates and coal mines. According to the statistics from 1977 to 1986, the annual average number of impact pressures is about 3 times. A total of 60 miners were present, of whom 10 were killed. Although the risk increases with the increase of mining depth, the amount of rock burst has not increased due to technical safety measures and organizational management. In 1977 and 1978, a significant amount of coal and gas outburst occurred in No. With the liberation of mining, coal and gas outburst greatly reduced the number. Between 1977 and 1986, an average of seven coal and gas outbursts were recorded annually in West Germany. In these coal and gas
