Abstract

A down-the-hole device has been designed for gas dynamics analysis in coal. The device is manufactured based on the layout of a straddle packer with an adjustable interval. The device design is suitable for hydrofracturing and gas dynamics researches using the methods of indicator diagrams and pressure buildup and drawdown curves in package with relaxation of coal and rock mass by means of radially symmetric loading of hole walls in the hydrofracture interval.
