Problems solved by technology

One is that the density of wax is difficult to determine accurately, and the density of wax is generally taken as 0.9g / cm 3 However, there are differences in the density of different qualities and batches of wax, which will cause density measurement errors; second, due to poor diagenetic properties of loose rock ores, rock ores will drop slag or scatter when they encounter water. Soaking is carried out, and the underground rock ore is saturated with water, which will cause the weight of the rock ore to differ from the real situation underground, and then cause errors in the weight of the rock ore after wax sealing and the weight of the rock ore after sealing wax in water, resulting in density measurement The third is that the work efficiency of density measurement is low

Embodiment 1

[0034] Present embodiment provides a kind of method adopting fabric wrapping method to measure unconsolidated rock ore density, it comprises the following steps:

[0035] (1) Use non-woven fabrics to wrap loose rock ore;

[0036] (2), measure the weight of the loose rock ore of the fabric that the gained of measuring step (1) is wrapped with non-woven material;

[0037] (3), measure the weight of the loose rock ore in water that step (1) gained is wrapped with the fabric of non-woven fabric material again;

[0038] (4), utilize following formula (2) to calculate the density of described loose rock ore according to the weight of the loose rock ore wrapped with fabric and the weight of the loose rock ore wrapped with fabric in water;

[0039]

[0040] In formula (2):

[0041] δ is the density of unconsolidated rock ore;

[0042] δ 0 is the density of water, δ 0 =1g / cm 3 ;

[0043] P 4 is the weight of unconsolidated rock ore wrapped in fabric;

[0044] P 5 It is the...

Abstract

The invention provides a method for measuring the density of loose rock ores by using a fabric wrapping method. The method comprises the following steps: (1) wrapping loose rock ores by using a fabric; (2) measuring the weight of the obtained loose rock ores wrapped with the fabric in step (1); (3) then measuring the weight of the loose rock ores wrapped with the fabric in step (1); and (4) calculating the density of the loose rock ores according to the weight of the loose rock ores wrapped with the fabric and the weight of the loose rock ores wrapped with the fabric in water. The provided method is high in density measurement precision, simple and convenient, and high in working efficiency.

Description

technical field [0001] The invention relates to a method for measuring the density of loose rock ore by adopting a fabric wrapping method, belonging to the technical field of geophysical exploration. Background technique [0002] The traditional method of measuring the density of unconsolidated rock ores uses the sealing wax method. Its working method is: first measure the weight of the rock ore, then seal a layer of wax on the surface of the rock ore, measure the weight of the rock ore after sealing the wax, and then measure the weight of the rock ore in water after sealing the wax, since the density of the wax is known, it can be Use the formula (1) to calculate the rock ore density. [0003] [0004] In formula (1): [0005] δ is the density of rock ore; [0006] δ 0 is the density of water, δ 0 =1g / cm 3 ; [0007] δ k is the wax density; [0008] P 1 is the weight of rock ore; [0009] P 2 The weight after sealing wax for rock ore; [0010] P 3 Weight in...
