Title:
DISPERSION FOR DRILLING AND MINING METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2014134091
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dispersion for drilling, which is produced by dispersing a hydrolyzable resin material that shows high hydrolyzability even at a low temperature of 80°C or lower, further 60°C or lower, in an aqueous medium, and is used when underground resources are collected by a well drilling method such as a hydrofracturing technique, a rotary drilling method and a riser-less drilling method.SOLUTION: In the dispersion for drilling, polyoxalate is dispersed in an aqueous medium as a hydrolyzable resin material.
