STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1

what is the rock mass strength. Knowledge of roc k mass strength is also important in the design of support systems as discussed in the next set of notes with regard to the concept of rocksupport interaction. In general, rock mass strength depends on the strength of intact rock and the strength of rock discontinuities.

v117n6a9 The needle penetration test for predicting coal

The coal strength parameter is used in operations such as the selection and design of mechanical excavators and coal crushing/grinding equipment. However, coring or cutting prismatic specimens from coal for the standard strength tests is difficult, and sometimes not possible. For this reason a method for the indirect determination of coal

Unconfined Compressive Strength Test of Rock

This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. Unconfined Compressive Strength Test Procedure Check the ability of the spherical seat

However, this technology has not found wide acceptance because of the relatively lower extent of improvement in coke strength and high costs involved in coal crushing installation and maintenance. The main constraint of selective crushing is the frequent clogging of screens on account of screening of fine coals (Chatterjee et al., 1982).

Crushing properties of coal SpringerLink

Abstract. Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most expedient.There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.

The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indiors of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion. Refractories with high CCS are also expected to have higher
