In the mutilphysics environment,the heat and mass transfer for VOCs of the indoor materials interior is effected by porous wall and the cross cpupled diffusive effect of temperature and humidity;The dependence of Darcy,Buoyancy ratio,extra heat and mass diffusive effect on heat and mass transfer of indoor VOCs are analyzed based on finite element method.

For water-uncouple charge,detonation wave shocks and presses water and stimulates shock wave,transmitting blasting pressure to rock through water and so its pressure of bore wall descended;for air-uncouple charge,however,products of detonation swelled and filled whole bore and then effects bore wall and its pressure of bore wall is the smallest among the three condit.
