The influence of solid volume fraction,gas volume fraction and foaming agent on the rheological property of foam slurry of gangue were investigated.

It is specially used to compound foam fluid and foam mud in versatile air drillings.

Bore-hole pressure calculation formula is discussed,bore -hole pressure drop factor is defined Press-sure,pressure drop factor and foam mud density are calculated at different depths in the given condition;a curve is drawn ;maximum pressure drop facto applicable depth are determinded.

In order to overcome the random of the foam diameter in the foam mud thick liquid and to improve the stability of the foam mud thick liquid, the turbine foam scattring cutting machine is designed.

A comparison is made on warp breakage between conventional sizing and foam sizingthrough practical weaving conducted under parameters obtained from optimum technologyof quadratic common rotatable combined design,in which three indexes are proposed toevaluate the quality of sized yarn.
