* Copper falls 0.6 pct on LME, 0.7 pct on ShFE * Freeport's mines in Indonesia and Peru plan strikes * Coming up: U.S. ISM N-Mfg data, Aug; 1400 GMT (Updates prices, adds quotes and details) By Carrie Ho SHANGHAI, Sept 6 (Reuters) - Copper fell by as much as 0.7 percent on Tuesday, hit by a slump in equities triggered by fresh fears about the euro zone's sovereign debt crisis, but supply disruptions from planned mining strikes could shore up prices. Two planned strikes at Freeport McMoRan Copper & Gold's mines in Indonesia and Peru this month are expected to deepen concerns over supply and bolster prices, traders said. Three-month copper on the London Metal Exchange fell 0.6 percent to $8,910.25 a tonne by 0338 GMT, after hitting its lowest level in a week in the previous session and then closing down 1.3 percent. The most-active November copper contract on the Shanghai Futures Exchange SCFc3 fell 0.7 percent to 66,630 yuan per tonne, led by a drop in the Shanghai Composite Index , after falling 1.1 percent in the previous session. "It looks like today's influence is mostly due to what is happening in the euro zone as there are no new developments in China or in the U.S.," said Dongzheng futures trader Du Xiao Hua. But investors are also increasingly nervous about another global economic recession, as that is likely to crimp demand for commodities. Latest data showed that global growth in services came to a virtual standstill last month. World leaders have been publicly voicing their concerns over the slow handling of the debt crises in the United States and especially the euro zone, where politicians have locked horns over bailout plans for Greece. The deputy heads of the financial regulatory agencies of China, Japan and South Korea plan to hold a conference call on Tuesday to discuss better ways to deal with the current uncertainty involving the United States and euro zone countries. Possible supply disruptions may help put a floor on copper prices, as Freeport's Grasberg mine in Indonesia, the world's third-largest copper mine, faces an indefinite strike from Sept. 15 unless the firm gives workers a pay rise, a union official told Reuters on Monday. Workers at the company's Cerro Verde copper mine in Peru will launch a 48-hour strike on Sept. 7 to win higher salaries, union representatives said on Friday.
