July 20 (Reuters) - Coal miner Yancoal Australia Ltd cut its 2022 output forecast on Wednesday, after reporting a fall in first-half production, hurt by higher-than-expected rainfall, COVID-19-led labour shortages and cost pressures.

The company, which is subject to a potential takeover by China's Yankuang Energy , said it now expects 31-33 million tonnes of attributable saleable coal production for the full year, down from an earlier forecast of 35-38 million tonnes. (Reporting by Shashwat Awasthi; Editing by Amy Caren Daniel)
