In order to reveal the immanence mechanism of macroscopic distortion and crack of the silo wall,the flow state of particles,dynamic stress of the wall and distribution network of interior granular material pressure are simulated with the distinct element method in the process of discharge from raw coal silo in power plant.

Deformation,cracking and vibration phenomenon have appeared in raw coal silo of a thermal power plant.

This paper expounds in detail the structural design of raw coal loading bunker, including the force analysis and calculation of the building above top of bunker, the top of bunker, the wall of bunker, the bottom of bunker, the supporting structure of bunker bottom, and the foundation, etc.

This paper introduces slipform construction of large diameter raw-coal buffer silo wall in Yuhua Coal Mine.

Discussion on rational millisecond time for sectional blasting of full depth of mine underground coal bunker;

The comparison of the two disposal schemes of coal bunker ground treatment with different ground conditions;

Determination on bunker cross centre line in construction;

Notice of the use of cylinder spiral inclined trough bunker;

Analysis and solution of coal jamming in bunker

Grouting reinforcement construction technology for the soft rock of coal bin;

The geologic conditions of coal bin and selection conditions of coal bin support are introduced.

There are some problems in the conventional conctrution methods in the coal bin of mining area.
