Based on applying instance of an exploration project in Mayingbao minefield,checked existing control points by GPS-RTK surveying technology analyzed survey precision and source of error of GPS-RTK surveying system,discussed error reducing and precision improving approaches.

Wangying Mine Field is a synclinal water retaining structure buried at great depths.

Developing geologic research and applying new techniques and improving Majing gas field;

Fracturing treatment is difficult in the JP_3 reservoir of the Majing gas field for its low permeability,deeply-buried reservoir,high pressure and thin reservoir thickness.

Lost circulation often has taken place in Majing gas field.

Preliminary discussion on regularities of fault development in Malan District;

After comprehensively studied regional geology,stratigraphy,sedimentary structure,paleontology and coal measures distribution in the Changchengwopu minefield,coastal and shallow lake sedimentary types and sedimentary environment evolution process were determined,that is the theoretical basis of coal seam hosting regularity,mine design and production,to tap the resources potentials.
