The bombs must be removed before the northern town's mainly Yazidi residents -- members of a minority group who were targeted in a brutal campaign of massacres, enslavement and rape by IS -- can return and begin rebuilding their lives.
Kurdish regional president Massud Barzani yesterday announced the "liberation of Sinjar", a day after the launch of a major ground operation to drive out the jihadists.
"Until now, we defused 45 bombs and a car bomb," said Sulaiman Saeed, a member of the autonomous Kurdish region's peshmerga forces who works in explosives disposal.
"Now that they've seized Sinjar, or freed Sinjar, the next phase is to go back and clear it," Colonel Steve Warren, spokesman for the international operation against IS, told a news conference yesterday.

"That will take a while, that will probably take a week, 10 days, maybe even two weeks, depending on the complexity of the minefields and obstacles that (IS) left behind," Warren said.
But bombs are not the only obstacles to a return by residents, as many houses and shops were smashed during the fighting.
Based on information from young women who witnessed the executions and were enslaved by IS but later escaped, officials on Saturday found the site of a mass grave believed to hold dozens of Yazidi women killed by the jihadists.
Miyasir Hajji, a local council member for Sinjar, told AFP that the grave on the edge of the town, which has not yet been excavated, is thought to contain the bodies of 78 women aged from 40 to around 80.
"It seems that the (IS) terrorist members only wanted young girls to enslave," Hajji said, referring to the jihadists using women as sex slaves who can be bought and sold.
The ground operation to drive the jihadists out of Sinjar, which began Thursday morning, was led by peshmerga forces and also involved Yazidi fighters, with support from US-led air strikes.
