Study on the processing technology of Wine Fried Dipacus;

The contents of tannic acid of different processing samples of Semen Arecae were determi ned with casein and the result s showed that different processing technology can affect the tannic acid content in some degree: improving temperature and due timing can make the content go up , vice versa.

Objective To optimize the processing technology of decoction pieces of Fructus Corni.

Our study researched the processing procedure, quantitativestandard and pharmacology of two slices of Rhizoma Sparganic------Rhizoma Sparganic flake and Rhizoma Sparganic with vinegar.

1 This research mainly concerns with the processing procedures, quantitative standard and stability of Dryopteris Crassirhizoma.

Inter-relation between blasting mining face prop supporting and drawing;

The management method of mining technique is introduced at the blasting face of thin coal seams,with 1.

Combining actual face circumstance,elaborates key technique processing for high gas face with compound roof so as to guarantee safe production of coal mine,which solves the dificult preblem of gas govenence at blasting face with compound roof and high gas.

The characters, damage and cause of rib fall at blasting face were analysed, and preventive measures were put forward, which has some reference value for other similar condition mines.

Research on mining technology of combined mining at large inclined angle "three soft" coal seam

That is to say,with the increased length in strike,improved mining technology,improved gateway layout,optimized production system and others,the mining rate in th.

According to the up an d down coal mining face features and the advanced experiences of the combined mining for seams with a closed distance at home and broad,the paper rationally set the mining technology and the alternate distance for the up and down seam mining.
