Coal mine explosions: seasonal trends
Science (New York, N.Y.)
|March 2, 1973
Summary
Coal mine dust explosions are more frequent in dry fall and winter months due to lower moisture levels. Gas explosions, however, occur randomly throughout the year.
Area of Science:
- Mining safety
- Combustion science
- Environmental impact on industrial accidents
Background:
- Coal mine explosions pose significant risks to personnel and infrastructure.
- Understanding the seasonal patterns of different explosion types is crucial for effective safety protocols.
Purpose of the Study:
- To analyze the temporal distribution of coal mine explosions.
- To identify environmental factors influencing the frequency of gas versus dust explosions.
Main Methods:
- Analysis of historical coal mine disaster reports.
- Correlation of explosion occurrences with seasonal weather patterns, specifically moisture levels.
Main Results:
- Gas explosions exhibit random annual distribution.
- Dust explosions show a statistically significant increase in frequency during dry fall and winter months.
- Reduced ambient moisture in colder seasons exacerbates dust explosion severity.
Conclusions:
- Seasonal variations in humidity are a key factor in coal mine dust explosion occurrences.
- Targeted preventative measures during dry periods can mitigate dust explosion risks.
- Distinguishing between gas and dust explosion patterns aids in refining mine safety strategies.

02:41Constant Volume Calorimetry
Calorimeters are useful to determine the heat released or absorbed by a chemical reaction. Coffee cup calorimeters are designed to operate at constant (atmospheric) pressure and are convenient to measure heat flow (or enthalpy change) accompanying processes that occur in solution at constant pressure. A different type of calorimeter that operates at constant volume, colloquially known as a bomb calorimeter, is used to measure the energy produced by reactions that yield large amounts of heat and...
02:14Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes
The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified petroleum gas (LPG), fuel oil, gasoline, diesel fuel, and...

01:25Interpreting Run Charts
Run charts, essentially line graphs plotted over time, serve as fundamental yet effective tools for process analysis. They chronicle data sequentially, facilitating the identification of trends, shifts, or cyclical movements. This graphical representation is instrumental in determining whether a process is stable or exhibits signs of potential instability indicative of special cause variation. In the healthcare domain, run charts depict infection rates over time, enabling hospitals to monitor...
01:12Run Charts
Run charts serve as an essential instrument for visualizing the performance of various processes over time, enabling the identification of trends and patterns crucial for quality improvement. These charts map out a series of data points chronologically, offering insights into the stability and efficiency of a process. A run chart's creation involves plotting data points on a graph, with the time intervals on the horizontal axis and the specific measurements on the vertical axis. For example,...
01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
01:15Quarrying of Stone
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the block.
