Эта компания знает всё о взрывах.
White Industrial Seismology, Inc. has been in continuous operation since its founding as White Engineering Associates, Inc. by industry pioneer Harold H. White in 1951. From inception, our primary goal has been to provide independent, professional, problem-solving, state-of-the-art vibration monitoring equipment and data analysis services.
In 1970, Harold White sold his interest in the company to David Bowling, a geophysicist and explosives specialist. Dave was instrumental in establishing White as one of the premier vibration monitoring firms in the mid-west. He and his wife Louise operated White until their deaths in the early 1990s. Today, White is owned and operated by Randy and Marla Wheeler. They have both been instrumentally involved in the business since the late 1970s.
Today, White offers both instrumentation and services. The Mini-Seis III™ takes us into the realm of engineering vibration equipment. The legacy Mini-Seis™ continues to be the blasting vibration monitor of choice for users around the world.
Our services include pre-blast and post-blast surveys, vibration monitoring programs, special vibration studies and seminars. Over the years, White has effectively met the vibration monitoring and analysis needs of numerous mines, quarries, construction companies, local, state and federal agencies and insurance carriers.
Our mission is to be the leading provider of vibration monitoring services and equipment through quality and commitment to professionalism.
Seismograph Data Analysis™ Анализ данных сейсмографа
We provide a complimentary advanced downloading and analysis software package with every seismograph. We also make it easy to download the software from our website. No dongles or complicated licensing agreements are required.
Well before the advent of electronic detonators, we saw relationships between blast timing and frequency. By varying the timing, we could effect a change in the vibration frequency content and the amplitude. Alpha-Blast was first developed using this concept. When electronic detonators became readily available, we saw Alpha-Blast rise to its full potential.
Now there are many more such applications, but we believe that Alpha-Blast was the first commercially available application for the blasting industry. They all tend to work on the same principle of superposition. A single hole is detonated which generates a signature waveform which is then used to model the probable effects of timing on a multi-hole blast.
Alpha-Blast provides the ability to look at the results of thousands of delay combinations. However, we look at more than just PPV and frequency. We also look at displacement and a unique concept we call the high to low frequency ratio. This ratio has proved invaluable to mining operations that want to manipulate their vibrations in order to maintain greater slope angles safely.
Alpha-Blast also allows the user to dynamically change timing and immediately see the results. If desired, it can utilize propagation velocity and coordinates to account for spatial distribution in vibration arrival times. It can also scale the models based on a custom scaling equation. Pattern designs can be developed quickly and easily. Custom patterns can be imported.
While the software will work best with data from our seismographs, it can also work with data from virtually any seismograph. A trial license is available upon request.
In-House Data Reporting
The same process we use to provide our Reporting Service can be hosted by your organization. To do this the following will be needed:
Your office network will need a static IP or DNS assignment
The office network firewall will need to be setup to allow data in from your monitoring stations
The White seismograph will need to be connected to a remote access device capable of port forwarding data via TCP to your office network.
The remote access device should have a static IP or dynamic DNS assignment
The White seismograph will need to be programmed to report data.
The vast majority of customers elect to use our Reporting Service because it is inexpensive and requires little effort on their part. However, for those customers who prefer to be more hands on, the AutoReceive software provides that ability.
AutoReceive VM should be used with the Mini-Seis III Pro or Mini-Seis III. It does not support the Mini-Seis. V2 supports the Mini-Seis and Mini-Seis III.
Compu-Blast™ ( Устаревшая)
Compu-Blast is a very easy program for laying out patterns and calculating timing. It features the ability to individually load holes, animate timing, summarize data, has a basic blasting log and many other useful reports and analyses.
Compu-Blast™ Design and Timing Analysis
The Compu-Blast™ software aids in the layout of blast patterns and the calculation of timing. A sample features list includes the following:
Layout designs with thousands of holes and a variable number of decks per hole.
Each hole can have a different diameter, depth and number of decks.
Variable row spacing.
Number holes in any manner.
Set a custom coodinate system.
Load holes with as many explosives per deck as needed.
Associate a blasting log with each design.
Animate the firing times from the Design Window.
Draw or remove holes and lines of holes with ease.
Move and copy lines of holes.
Copy data from any hole to a line of holes.
Import design data from a delimited text file or from a Compu-Blast V8 file.
Designs are conveniently stored in a single database.
Produce numerous design and timing reports.
Save design times for use with the Alpha-Blast program in order to produce vibration simulations based on signature waveforms.
Regressiion analysis from vibration data supplied in blasting logs.
