The Science of Limestone Operations

Limestone operations are tightly regulated, extensively monitored and routinely reviewed by independent agencies and experts.

Tightly Regulated

Here's how it works

Step 1: Preparation

Document Review

Experts review everything from permit and project specifications to excavation plans and permitted blast times.

Site examination

Professionals must evaluate field conditions—from surface and groundwater to any geological irregularities.

Step 2: Planning

 
During the planning phase, mining professionals must determine blast hole pattern and detonation sequence.
Both are optimized to break the rock efficiently and to minimize ground vibration and sound.

Step 3: Implementation

  1. Highly trained operators dig small, precise holes in the rock.
  2. The holes are then filled with a blasting agent.
  3. Operators connect the detonators.
  4. Safety experts secure the blast area.
  5. A highly-coordinated detonation follows, producing energy that travels through the rock and causes it to break, allowing for extraction.

Monitoring


Blasting crews, regulators and independent seismologists monitor all operations using highly sensitive seismic instruments.


We use advanced blasting technology to ensure our operations are well within safe limits.

3 Things to remember

  1. Highly trained experts oversee the mining process from start to finish.
  2. Our blasts stay consistently below state limits, which are 62 percent stricter than the national levels established by the U.S. Bureau of Mines.
  3. Technological advances, including sophisticated electronics and micro-seismographs have greatly increased control, limited vibrations and reduced frequency of blasting.
