The paper introduced the principle of the strata stress measurement with hydraulic cracking and the certain application at the site. With the site strata stress measurement, important basic parameters can be provided for the initial design of the mine roadway support. The practices showed that the results of the stress measurements had important significances to improve the science and reliability of the mine roadway support design.
