近年,分布式光纤传感技术得到快速发展,并且逐渐从实验研究走向实际应用,目前已成功应用于土木工程、安全防护、军事、交通等领域。这项技术已成为光纤传感技术中最具前途的技术之一。目前,我国正处于经济的转型期,随着工业化和市场经济的快速发展,我国能源需求量不断增加,煤炭产量从2000年的9.99亿吨增加到2007年的25.23亿吨。尽管社会经济发展水平和安全技术装备水平都在不断提高,政府、企业及整个社会更加重视安全。法律法规的约束、监察监管力度更大,但是煤矿安全生产形式依然十分严峻。我国是世界上煤炭伤亡事故
In recent years, distributed optical fiber sensing technology has been rapidly developed, and gradually from experimental study to practical application, has been successfully used in civil engineering, security, military, transportation and other fields. This technology has become one of the most promising technologies in fiber optic sensing. At present, our country is in a period of economic transition. With the rapid development of industrialization and market economy, the demand for energy in our country is constantly increasing. The output of coal increased from 999 million tons in 2000 to 2.523 billion tons in 2007. Although the level of social and economic development and the level of safety technology and equipment are constantly improving, the government, enterprises and society as a whole pay more attention to safety. Constraints of laws and regulations, supervision and supervision more, but the form of coal mine safety is still very serious. Our country is the world’s coal casualty
