A Chinese worker rides his bicycle in front of a poster placed outside a coal mine near the city of Datong, in China's Shanxi province, February 23, 2005. Despite increasing high-level attention to mine safety, including dismissal of officials who let accidents happen on their watch, it has proven nearly impossible to control the industry in the face of coal prices that jumped 40 percent last year to about a $60 a tonne. The poster reads: "Happy to work - safe to go home." Picture taken February 23, 2005. TO MATCH FEATURE CHINA-COAL. REUTERS/Reinhard Krause RKR/PN/DH
