Four bulks”(bulk loading,bulk transportation , bulk storage and bulk unloading) automation was discussed,and application of PLC technique to operating in silo at dock was introduced.

The test adopted the curve piecewise fitting method to build up a mathematic modelaccording to change regularity of phosphine gas release and concentration degradation in theprocess of silo recirculation fumigation.

Design and implementation of vertical shaft clearance and extension construction;

The purpose of this paper is to find the distribution laws of the shear force between vertical shaft and surface soil,and to lay a foundation for mechanical model of shaft in soil.

On the basis of experience on installation of Qujiang main shaft and auxiliary vertical shafts, the author attaches importance to some keys to the installation of vertical shafts.

An artificial neural network forecast model for shaft lining non-mining fracture;

of deep large shaft,the freezing construction technology was adopted.

Design of new harnessing method for shaft lining fracture of coal mining;

On the basis of the boundary displacement function,the state equation is established for the shaft lining whose upper edge is free and the opposite edge is clamped in deep alluvium under any axisymmetric load,and the solution is presented.

Non-mining fracturing of shaft lining is a special engineering geologic hazard and is caused by interaction between mining and geological environment.
