煤矿生产过程可能造成大量生命财产损失,如水患、水灾、瓦斯爆炸、煤尘爆炸、冒顶、矿震、冲击地压、机械和电气事故等等。尽管我国煤炭工业发布了大量的,可以说是苛细的安全法规,煤矿管理人员、技术人员做出了极大的努力,煤炭科研人员做了大量的工作,重大事故仍不断发生。我国1995年生产原煤12亿吨,死亡7000人,而同年美国生产商品煤9亿多吨,死亡44人。事实上中国的煤矿设备 Coal production process may cause a lot of life and property losses, such as floods, floods, gas explosions, coal dust explosion, roof fall, mine shocks, rock burst, mechanical and electrical accidents and so on. Although China’s coal industry released a large number, which can be described as harsh safety regulations, coal mine managers and technicians have made great efforts. Coal researchers have done a great deal of work, and major accidents continue to occur. In 1995, China produced 1.2 billion tons of raw coal and killed 7,000 people. In the same year, the United States produced more than 900 million tons of coal and 44 deaths. In fact China’s coal mining equipment
