Requirements Applicable to Underground Coal Mines § Scope of chapter. This chapter shall be applicable to the operation of any underground coal mine in the Commonwealth, and shall supplement the provisions of Chapter (§ et seq.). , c. § in-mine evaluation, the detectors occasionally identified conveyor Optical smoke detectors operate on the principle of scattering belt heating. Also, for a mine using diesel-powered equipment in which a comparison could be made with CO levels at the time of smoke detector alarm, the smoke detector had a lower frequency of false alarms than CO.

IN-MINE EVALUATION OF SMOKE DETECTORS By G. Morrow1 and C. Litton2 ABSTRACT This report presents the results of a U.S. Bureau of Mines evaluation of smoke detectors placed in conveyor belt entries of underground coal mines.
The selected mines are located in six different Mine. : In-Mine Evaluation of Smoke Detectors (Information Circular/Bureau of Mines, ) (): G.S. Morrow, C.D. Litton: BooksAuthor: G.S. Morrow. Six smoke detectors were measured with respect to visually obscuring smoke characterized by a corresponding optical density for smoldering and flaming coal combustion in the smoke chamber.
It was determined that for one type of ionization smoke detector the alarm time was nearly equivalent to that of an odor monitor's alarm for smoldering coal Cited by: 1. The report presents the results of an evaluation of smoke detectors placed in conveyor belt entries of underground coal mines.
The selected mines are located in six different Mine Safety and Health Administration (MSHA) Coal Mine Safety and Health districts; are operated by seven different companies; and use atmospheric monitoring systems from.
PDF | Experiments were conducted to evaluate the response characteristics of commercially available gas, smoke, and flame sensors to fires of common | Find. Immediately after visible flames were observed, the Spero sensor (S1) and the flame sensor alarmed.
This typical sequence of alarms reinforces the fact that photoelectric-type detectors (S4) are more sensitive to smoke from smoldering fires while ionization-type smoke detectors (S3) are more sensitive to smoke from flaming by: 1.

Highlights Coal mine fire can occur at any time and often results in partial or total evacuation of mine personnel and could result in the loss of lives. Having a warning system that is capable of detecting fire and generating an alarm is important. We present the response time of a proposed system for detecting fire hazard in a Bord-and-Pillar coal mine panel.

Demining or mine clearance is the process of removing land mines from an area. In military operations, the object is to rapidly clear a path through a minefield, and this is often done with devices such as mine plows and blast waves.
By contrast, the goal of humanitarian demining is to remove all of the landmines to a given depth and make the land safe for human use.

Belt entries used to ventilate working places should be equipped with carbon monoxide monitoring systems or smoke detectors. MSHA and the Bureau of Mines should encourage development and testing of improved smoke detectors.
MSHA should initiate the development of performance standards for CO monitors and smoke detectors.

Abstract. To understand the role of the human nose in the disposition of inhaled particles one must know the circumstances under which nasal breathing is practiced, the character of nasal air flow (or oral air flow when it occurs), what particles are deposited within the upper air passages, and their ultimate fate.
The global burden of injuries is enormous, but has often been overlooked in attempts to improve health. We review measures that would strengthen existing efforts to prevent and treat injuries worldwide. Scientifically-based efforts to understand risk factors for the occurrence of injury are needed and they must be translated into prevention programmes that are well designed and Cited by: The integrated cooling measure significantly reduces the TTD`s exterior IR signature.
