While President Mikhail Gorbachev watched a glum May Day parade in Moscow, his chief rival, Boris Yeltsin, was in Siberia signing an agreement bringing coal mines under his jurisdiction in an effort to end a nearly 9-week-old strike.

Gorbachev got only perfunctory applause Wednesday from about 10,000 workers marching in Red Square, but in Novokuznetsk about 10,000 Siberians cheered Yeltsin, the lesder of the Russian Federation, as he signed the pact taking Kuzbass coal mines under his republic's authority, the Russian Information Agency reported.The agreement also would permit the mines to keep 80 percent of their hard currency instead of the 6 percent now allowed by the Soviet central ministries, the news agency said.

Yeltsin said he hoped this could give the mines the economic independence that the miners have clamored for and end a strike that erupted March 1 and shut down at least one-fourth of the nation's coal mines.

The miners have from the very beginning backed Yeltsin's earlier calls for Gorbachev to resign.
