Transactions of the American Society of Civil Engineers, vol. LXX, Dec. 1910: Federal Investigations of Mine Accidents, Structural Materials and Fuels. Paper No. 1171

In Short

This document serves as a formal record of federal efforts to address the catastrophic loss of life in American coal mines at the turn of the century. By detailing the establishment of standardized testing for explosives and rescue equipment, the work illustrates the shift toward scientific regulation in the mining industry. It also broadens its scope to include the systematic analysis of fuel efficiency and structural materials, effectively marking the moment when rigorous civil engineering became a matter of national policy and public safety oversight.

The Story

The narrative begins with a haunting reminder of the human cost of industrial progress: the Cherry mine disaster of 1909, where hundreds of men were entombed. This tragedy provides the urgent context for the federal government’s intervention. The text traces the evolution from a period of unregulated, dangerous mining practices to a new era defined by the creation of the United States Explosives Testing Station in Pittsburg. The core argument is that through scientific observation, rigorous laboratory testing, and the deployment of specialized rescue crews, the government can transform a profession once viewed as inherently lethal into one governed by predictable, manageable risks.

The book details the transition from relying on guesswork to relying on data. It explains the specific requirements for "permissible explosives," which were tested for their tendency to ignite volatile coal dust or gas. The engineers move methodically through the mechanics of safety: they describe the use of oxygen helmets, the structural reinforcement of mine shafts, and the development of new methods for combating underground fires. The account does not shy away from the technical complexities of the task; instead, it invites the reader to understand the physical environment of the mine, from the chemical properties of gases to the precise pressure-gauge readings required to evaluate an explosive’s safety profile.

As the scope expands, the text explores how these same principles of efficiency and safety are applied to the nation’s broader industrial needs. The engineers detail extensive studies into the combustion of coal, the briquetting of lignite, and the structural integrity of concrete and stone. The vision presented is one of total scientific control over natural resources and materials. By the end, the reader is left with the understanding that the government’s role shifted from a passive observer to an active, technical participant in the economy. The concluding sections reiterate that while the full benefits of this research would take generations to manifest, the foundation for a standardized, safer industrial future had been firmly laid. It is a story of systematic institutional growth, where the goal of preventing disasters like Cherry, Illinois, drives an entire apparatus of testing, measurement, and regulation.

How It Unfolds

The mandate of safety The report opens by examining the failures of the mining industry in the wake of the 1909 Cherry disaster. It establishes that government intervention was not just a political choice but a technical necessity to prevent future loss of life.

Establishing the protocols The focus shifts to the creation of the Pittsburg testing station, where the rules for explosive manufacturers are codified. Here, the reader learns the exact parameters required for explosives to be deemed "permissible" for use in volatile environments.

The science of destruction and rescue Detailed descriptions of testing galleries and lead-block experiments demonstrate how engineers measure the shattering effect versus the heaving effect of powders. This section bridges the gap between laboratory results and the practical realities faced by miners in the field.

Broader structural investigations The scope broadens to include the testing of concrete, stone, and steel using massive hydraulic presses. The text explains how these materials are subjected to environmental stressors like salt water to predict their long-term performance in public infrastructure.

Fuel efficiency and economic utility The final movement details the transition from crude fuel usage to the sophisticated analysis of gas producers and briquette machines. The work concludes by emphasizing that these scientific investigations are essential for the efficient and safe development of the nation’s resources.

The People

Herbert M. Wilson acts as the primary architect of this report, framing the government’s technical findings with a sense of urgency born from the disasters he describes. He serves as the bridge between the high-level policy of the Geological Survey and the practical, gritty work of the engineers.

George S. Rice and J. W. Paul emerge as the men on the ground. As the leaders of the rescue division, their actions during the Cherry mine fire illustrate the practical application of their training. They are defined by their willingness to enter hostile, high-heat environments and their capacity to direct complex operations under immense pressure.

Richard L. Humphrey and H. H. Kaplan represent the structural wing of the project, focusing their efforts on the physical testing of building materials. Their work—often housed in expansive, specialized facilities—shows an obsession with precision, from the monitoring of concrete briquettes to the operation of massive compression machines. These figures are not characters in a traditional sense, but embodiments of a new, expert class of government employees who view the country’s industrial output as a set of variables to be solved through laboratory testing and standardized measurement.

In Its Own Voice

“The mine disaster, which occurred at Cherry, Ill., on November 13th, 1909, when 527 men were in the mine, resulting in the entombment of 330 men, of whom 310 were killed, has again focused public attention on the frequent recurrence of such disasters and their appalling consequences.”

The introduction provides the stark, human motivation behind the federal government's decision to intervene in mining safety.

“The preliminary investigation showed the necessity of subjecting to rigid tests all explosives intended for use in mines where either gas or dry inflammable dust is present in quantity or under conditions which are indicative of danger.”

This passage explains the logic behind the strict new regulatory standards for mining explosives.

“The results of such investigations as have been described in the preceding pages cannot be realized for many years; but, even within the four years during which this work has been under way, certain investigations have led to important results.”

These lines offer a realistic appraisal of the long-term nature of civil engineering research.

What It's Really About

At its core, this work explores the tension between rapid industrial expansion and the necessity of human survival. It argues that modern technology, while potentially destructive, can be harnessed through scientific rigor to protect the very people it threatens. The text explores the transition from a laissez-faire economy to one that acknowledges the state’s duty to regulate dangerous work environments. It asks: how can we quantify the risk of a mine explosion or the structural failure of a bridge? The underlying answer is that safety is not an abstract virtue, but a product of measurement, chemical analysis, and the institutionalization of expertise.

Why Read It Today

Readers with an interest in the history of technology, administrative policy, or the origins of OSHA-style regulation will find this volume invaluable. It is a primary source document, and as such, it possesses a dry, technical rhythm that reflects the seriousness of its subject matter. It does not contain dramatic character arcs; rather, it offers the satisfaction of seeing a massive, complex system of safety standards being built from the ground up.

A modern reader should be prepared for the dense, period-specific terminology and the sheer volume of tables and equipment descriptions. It is not light reading, but it provides a profound window into a pivotal era when science was first being systematically applied to the common welfare. The persistent focus on the "Cherry disaster" serves as a poignant anchor, reminding the reader that behind every pressure-gauge reading and every chemical formula lies a desperate, historical attempt to prevent the next great tragedy. You will walk away from this book with a new appreciation for the mundane, standardized testing that underpins the safety of our contemporary industrial world.
