This paper introduces slip-casting materials and the types of slip casting method,illustrates the theory of slip-casting technique as laneway strengthening method,introduces the application of slip-casting supporting in laneway construction from wall rock,strengthening by water shut off and economy,and points out the developing tendency of the technique.

Design of the shotcrete support for the underground powerhouse of Longtan Hydropower Station;

Variation characteristics of tunnel adjacent rock and shotcrete rockbolt support action;

The smooth blasting is the basic condition of the shotcrete rockbolt support, and is the fundamental work for guaranteeing the quality of the shotcrete rockbolt.

This paper makes deep analysis on the problems existing in the actual application of the bolt-spray supports in the sinking and driving engineering, and puts forward some methods and measures for solving these problems.

This paper sketches the popularization and application of the technique of smooth-wall blasting and bolt-spray supports in the tunnels of coal mines, and analyses the economic benefit obtained by popularizing and applying this technique in coal mines.

This paper presents the structure, function, and design method of the software package of a quality management information system of bolt-spray supports engineering.
