Shaanxi Coal Industry Co., a major coal miner, will debut on the Shanghai Stock Exchange today, in the biggest mainland listing since the initial public offering (IPO) market was reopened late last month. The company raised 4 billion yuan (US$660.97 million) via the IPO, down about 60 percent from a target set this month after the stock regulator stepped up its policing around IPO pricing behavior. China Securities, CICC and BOC International are the underwriters for the IPO.SD-Agencies
