QUEENSLAND Liberal National Party leader Campbell Newman is visiting a grain growing area in the sights of mining interests.

Bandanna Energy is eyeing Springsure, south of Emerald, for an underground coal mine.

Grain farmers there say former environment minister Kate Jones gave them an assurance the area would be protected from mining, and then reneged.

Mr Newman will meet growers and community members of the "golden triangle" today, as he considers an agriculture policy that balances the interests of food production and mining.

The opposition has written to miners and explorers, seeking discussions on the conflicts that are arising around the state.

Opposition mining spokesman Jack Dempsey said the current permit system required a portion of the approved exploration area to be relinquished every two years.

This meant resource explorers applied for much more land than they actually needed.

"In many cases, exploration permits are for areas that there is no intention to mine, including urban and other areas," Mr Dempsey said.

"All this practice achieves is to raise the hackles of town dwellers and puts a cloud of uncertainty over affected residents and landholders."

The LNP is considering an alternative that might reduce the size of the exploration permit areas.

Rural lobby group Agforce has welcomed the LNP's commitment to agriculture.

President Brent Finlay said he hoped it would last.

"Often agriculture is paid lip service while being overlooked for other profitable industries that directly compete for the same land that are our livelihoods," he said.

Queensland Resources Council chief Michael Roche said the state's resources sector delivered one in five dollars of state product, and one in eight jobs.

For this, it uses 0.09 per cent of the state's land mass, he said.
