Determination Of The Total Grain Size Distribution In A Vulcanian Eruption Column, And Its Implications To Stratospheric Aerosol Perturbation, P. J. Murrow, William I. Rose, S. Self

Department of Geological and Mining Engineering and Sciences Publications

Grain size analysis of samples representing all sampleable portions of the airfall deposit produced by the Fuego volcano in Guatemala on 14 October 1974 form the basis for estimating the total grain size distribution of tephra from this eruption. The region enclosed by each isopach has a particular average grain size distribution which can be weighted proportionally to its percentage volume. The grain size of pyroclastic avalanche deposits produced during the eruption are also included. The total grain size distribution calculated as a sum of weighted distributions has a median grain size of 0.8∅ (0.6mm) and a sorting coefficient (σ∅) …

Umr Minerals Building: An Innovative Approach To The Construction Of Underground Buildings, Bruce H. Green, David A. Summers

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The original intent of the exercice was to develop a design for a new minerals engineering building which would demonstrate the applicability and feasibility of an underground building complex to our administration and to the Board of Curators. Two major advantages were foreseen for such a building. Not only would it be immensely superior, in terms of energy demand, to the conventional aboveground buildings previously constructed by the University, but it also would have highly significant symbollic and educational effects on the students of the several disciplines comprising the UMR "School of Mines and Metallurgy". It would also serve as …

Determination Of Washability And Flotation Characteristics Of Important Missouri Coal Seams, Hayri Erten

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Most of the 14 workable coal seams in the State of Missouri are considered to be high in ash and sulfur contents and need beneficiation in order to meet customer and Environmental Protection Agency requirements. If proper beneficiation methods can be designed, more Missouri coal will be mined and used within the state.

The objectives of this research are (1) to draw the washability curves of important Missouri coal seams in order to determine their washability characteristics, and (2) to determine the flotation characteristics of the same seams.

Tests conducted on 20 samples taken from Bevier, Croweburg, Mulky, and Summit …

Federal Lands, Laws and Policies and the Development of Natural Resources: A Short Course (Summer Conference, July 28-August 1)

Even before the [Natural Resources Law] Center was established [in the fall of 1981], the [University of Colorado] School of Law was organizing annual natural resources law summer short courses. To date four programs have been presented:

- July 1980: "Federal Lands, Laws and Policies and the Development of Natural Resources"

- June 1981: "Water Resources Allocation: Laws and Emerging Issues"

- June 1982: "New Sources of Water for Energy Development and Growth: lnterbasin Transfers"

- June 1983: "Groundwater: Allocation, Development and Pollution"

(Reprinted from Resource Law Notes, no. 1, Jan. 1984, at 1.)

Instructors for this conference included University …

We Eat The Mines And The Mines Eat Us: Dependency And Exploitation In Bolivian Tin Mines (Book Review), Melvin Burke

School of Economics Faculty Scholarship

This book is about the high human cost of producing tin and other minerals. June Nash vividly describes the arduous physical labor and life of Bolivian miners in the physically inhospitable Andean mountains. More than an anthropological account of indigenous miners in far-off Bolivia, the book is a serious rendering of the contemporary social, economic, and political reality at the industrial world periphery. It is a unique blend of disciplines, paradigms, and philosophies which moves one back and forth in time and space and thought. Nash is able to tie this all together by permitting the miners to speak for …
