During an investigation of the mineralization of the Leadhills- Wanlockhead lead and zinc mining district, rammelsbergite (NiAs2) was identified as an associate of niceolite (NiAs), reputed to have come from no. 4 level on the west branch of the New Glencrieff vein. The identification was confirmed on further material collected from the dumps at the Glenerieff mine, Wanlockhead, Dumfriesshire, and on specimens from the Scottish Mineral Collection (nos. 1952.5.18; 20; 21).

A prospecting method used in 1975 in Greenland and reported briefly on here measures the total cold extractable amount of seven heavy metals, Zn, Pb, Cu, Co, Ni, Sn and Ag. The primary aim of the method is to discover and outline metal anomalies but not to determine their metal content accurateIy. Once an anomaly is targeted this can be done by more detailed foIlow-up surveys. The two areas chosen to test the suitability of the method to Greenland conditions, were the lead-zinc mining district of Mesters Vig on the east coast and the Sorte Engel (Black Angel) mine at MârmoriIik on the west coast. The traverses run show strong anomalies over kriown veins (figs 37 & 38, AA' & CC'; fig. 39, GG' & HH'), as well as indicatingpreviously unknown mineralisation (fig. 38, BB'; the western anomaly in fig. 39, HH').

Siberian Department

In 1877, the creation of the West Siberian Department of the Russian Geographical Society in Omsk marked a new stage in the history of scientific study of the Altai Mining District, which was expressed, among other things, in the active expeditionary activities of that time leading scientists to the region. The article analyzes the publication's content of the department's printed organ — «Notes», dedicated to the colonization process and migrations of the second half of the 19th century. The content of the works on the theme, their specificity, and their role in shaping the resettlement agenda are identified. It is emphasized that despite the positive assessment of the role of migration in the development of the Altai territory, experts of the turn of the 19th-20th centuries identified bifurcation points in the work of the «pro-gram» of peasant development of the territory (the relationship with the local Russian and foreign population, the agricultural potential of hotel lacunae, the impact of migration on the scrapping of the type of land use consistent with the natural and climatic conditions of the region, land crowding, rapid plowing of soils, etc.). The article concludes about the unique nature of field materials, their «live» content, the desire for fixation and objectification.

Water Bursting

Collapse column water bursting occurs from time to time in the coal mining process of North China Type Coalfield in China, which causes great economic loss and personal injury. Therefore, great attention must be paid to the harm of collapse column. 1301 working face and 1306 working face in the west wing of No.1 Mining District of Zhangji Coal Mine in Shanxian County are close to No.2 collapse column. Water bursting risk evaluation must be carried out before mining two working faces to ensure safety production. On the basis of fully analyzing the geological and hydrogeological conditions of the 3up coal seam in the west wing of No.1 Mining Area, the "Three Zones(caving zone, water conducted fracture zone and sagging zone) Theory of Coal Seam Roof", "Strata Movement Theory" and "Water Bursting Coefficient Theory" were used respectively to calculate and evaluate the water bursting risk of No.2 collapse column during the course of mining the 1301 working face and 1306 working face. The results show that: firstly, in the process of mining the 1301 working face, the maximum height of the water conducted fracture zone at the closest position of 1301 working face to No.2 collapse column would be 60.20 m, the water bursting coefficient on the boundary of water conducted fracture zone would be 0.066~0.072 MPa/m, and the water bursting risk of the No.2 collapse column would be smaller; secondly, in the process of mining the 1306 working face, the maximum height of the water conducted fracture zone at the closest position of 1306 working face to No.2 collapse column would be 60.91 m, the water bursting coefficient on the boundary of water conducted fracture zone would be 0.057~0.089 MPa/m, and the water burst risk of the No.2 collapse column would be small. By August 31, 2020, the 1301 working face had been safely mined more than 200 meters long(exceeding over 120 m of the closest position in 1301 working face to No.2 collapse column), and the water bursting did not happen in the working face. This paper can provide a reference for the water prevention and control of similar collapse columns in coal mines.
