Pollution control and protection of the karst water in Jincheng;

Environment isotope determination mode for Karst water under seam floor of Wanbei Mining Area;

Simulation and analysis of karst water environmental system in Taian city;

But because of the floor elevation of the lower coal group is generally lower than the Ordovician limestone karstic water table,together with complicated structural and hydrogeological conditions in the mining area make up of threatening to the mining of lower group coal.

The article combine with the project example to introduces the investigation method of karstic water source place.

With the water\|rock chemical equilibrium model WATEQ4F as the basic program and with a typical karstic water point in Pingdingshan mining area selected,the error transmission of the hydrochemical analysis data input in the water\|rock chemical equilibrium simulation was studied.

Mode of occurrence of karst groundwater in the Northern Shaanxi Energy and Chemical Industry Base, China and its influence factors;

A practical use of ~34)S in the investigation of karst groundwater resource in North China

The abundant karst groundwater resources in a city of North Henan and the tendency of increase in chloride concentration in the karst water are briefly introduced in this paper.

Mining experiment of upper coal seam under Changxing karst aquifer in Fengcheng Mine Area;

Drainage in a reverse slope is the primary problem in the construction of a tunnel in a reverse-slope stratum with abundant water.

In tunnel construction of rich water karst area,the key technology to guarantee the tunnel construction security is to detect and forecast the geological situation in front of the tunnel face.
