Company to declare a kind of high pressure gas impact source locks for a patent for invention,
won the state intellectual property office of the invention patent authorization; Joint, another kind
of goaf multiwave seismic exploration method, artificial surface wave excitation source instant
impact and high pressure gas source automatic escape from filing an application for a patent
for invention has won the state intellectual property office of the accepted.
A kind of high pressure gas impact source lock is used in a portable, easy to carry, safe and
simple operation, convenient use, large excitation energy, wide frequency range, high frequency
composition is rich, high efficiency, low cost of explosion type, impact of electromagnetic new
type of high pressure gas source of the energy storage and release can device. The locks in
the impact of high pressure gas source through the lock and unlock the hammer head rod,
the energy release can device security, play a role of energy release can effectively. Impact
of high pressure gas source has won the state intellectual property office utility model patent
A goaf joint multiwave seismic exploration method using the reflection wave method, scattering
wave, and refraction tomographic imaging method, common offset method, double source
surface wave method, joint multiwave technologies such as underground goaf detection provides
a kind of fast, efficient, high precision, low cost of exploration methods, the detection results
can support each other, complement each other, to detect the distribution of mined-out area.
An artificial surface wave excitation source instant device is used in a kind of simple operation,
easy to use artificial surface wave excitation source of energy storage and release can device.
The instant is at the top of the lock and unlock by dropping heavy earrings, make the heavy
security, play a role of energy release can effectively.
A high pressure gas shock source automatic escape is to avoid the secondary impact excitation
device. Through effective to extend the time interval to the impact on the ground for the first
time, make the second on the ground impact energy of elastic wave is abate, and not into the
effective records; At the same time, effectively reduce the source of the hammer body rigid
collision, reduce fatigue parts material, prolong its service life.
